    This paper reports the results of an inquiry conducted to a sample of homes of a group of dwellings. The objective of this inquiry was to know the number of dwellers, the electric household appliances and the type of artificial lighting characteristic of a three-bed room apartment of approximately 65 square meters. In the Introduction is given the information related to the distribution of the monthly consumption of the entire group of dwellings for two separate periods for more than six years, which allows to determine the yearly average rates of growth. The information collected in the inquiry is presented in graphical form of frequency of electric household appliances and the light bulb rating of the more typical electric appurtenances. The results correspond to the answers in 188 inquiries judged reliable (230 questionnaires were delivered to the homes). The analysis of the information allows the knowledge of the electricity consumption capacity that the sampled homes have and to infer the consumption capacity of the entire group of dwellings.

    This paper analyses the changes in equipment in dwellings and the residential energy consumption for end uses in Mexico in the 1984-1994 decade. The study is based in data of the Instituto Nacional de Estadistica, Geografia e Informatica (INEGI)`s Income-Expense in Homes National Survey and in estimates of the unit consumption of the household appurtenances. The most important results show that food cooking represents 64% of the residential energy consumption, 22% water heating, 4% lightning and 10% electric appurtenances and other uses of LP gas and natural gas. The devices of greater saturation in 1994 were the gas stove (87%), the iron (85%), the TV (85%) and the refrigerator (64%). In analysis of the equipment there is a serious inequity in the country. The number of dwellings that have electric household devices or appurtenances requiring the supply of energy services greatly depend on the income level of the same. [Espanol] Este articulo analiza los cambios en el equipamiento de las viviendas y en el consumo de energia residencial por usos finales en Mexico en la decada 1984-1994. El estudio se basa en datos de la Encuesta Nacional Ingreso-Gasto de los Hogares del Instituto Nacional de Estadistica, Geografia e Informatica (INEGI) y en estimaciones del consumo unitario de los equipos. Los resultados mas importantes muestran que la coccion de alimentos representa el 64% del consumo de energia residencial, 22% el calentamiento de agua, 4% la iluminacion y 10% los equipos electricos y otros usos de gas LP y gas natural. Los equipos de mayor saturacion en 1994 fueron la estufa de gas (87%), la plancha (85%), la television (85%) y el refrigerador (64%). En un analisis de equipamiento por nivel de ingreso, se muestra que existe una inequidad grave en el pais. El numero de viviendas que cuentan con equipos para suministrar servicios energeticos depende enormemente del nivel de ingreso de las mismas.

    The saving and rational use of the energy is integral part of our life. This concept is seen already reflected in economic, technological, social and environmental factors in our country. The options of energy saving are seen like an alternative of investment as much for the user as for the electrical companies; nevertheless, to determine the saving potential in a sector it is necessary to understand how and for what purpose is the energy used. The domestic sector in our country consumes more than 20% of the demanded electrical energy and exist several factors that can cause that this percentage is increased. In spite of this, there is a great potential of energy saving in this sector, nevertheless specialized studies are required on the final uses of energy. But to be able to make these studies it is necessary to have a great amount of data on energy, climatologic, economic and financial, and social type. If these were found in a single data base, they could be used to plan, implement, evaluate and improve energy saving programs. This article focuses towards the importance of the knowledge of the real final uses of electrical energy in the domestic sector and presents as a result the conformation of a data base of household-electric final uses of electrical energy as well as the development of a tool that takes advantage of this data base to evaluate measures of change of equipment for a more efficient one.

    The interest of building industry to improve the standardization of building processes result in a increasing tendency of using the gypsum as boards, and as a projected gypsum mortars. On the other hand, the need of reuse industrial wastes to avoid environmental impact resulting of their deposition and to reduce the management costs, indicates the building industry as an important user of large quantities of industrial wastes, mainly that generated in the ore milling The industry of phosphate fertilizers is a typical example of this interaction. The phosphate rock milling through the wet process, reacting phosphate rock with sulfuric acid, produces substantial quantities of calcium sulfate as a by-product known as phosphogypsum, that are stored in stockpiles. The phosphate rock contains radionuclides of the U and Th decay series. During the chemical attack these radionuclides are distributed in different proportions between the phosphoric acid and the phosphogypsum. This work presents the radiological characterization phosphogypsum, produced by two national fertilizers industries. A methodology to quantify the radiation exposure, in a reference dwelling , due the use of phosphogypsum considering different scenarios, was established. The external irradiation and the inhalation of radon and thoron and their decay products in indoor air were considered. The values of individual effective dose equivalent ranged from 0.12 to 1.95 mSv.a{sup 1}, depending on the phosphogypsum origin and the scenario considered. About 80% of the dose rises from the inhalation of thoron and its decay products. The results show the importance of Th series radioactive disequilibrium in the assessment. Depending on the phosphogypsum origin and scenario of use, the dose values justify the control of this practice. The general conclusion is that this practice have to be considered case by case and the proposed methodology is suitable to assess the dose and the radioactive disequilibrium

    2006-01-01

    In this paper, we consider the relation between the switching dwell time and the stabilization of switched linear control systems. First of all, a concept of critical dwell time is given for switched linear systems without control inputs, and the critical dwell time is taken as an arbitrary given positive constant for a switched linear control systems with controllable switching models. Secondly, when a switched linear system has many stabilizable switching models, the problem of stabilization of the overall system is considered. An on-line feedback control is designed such that the overall system is asymptotically stabilizable under switching laws which depend only on those of uncontrollable subsystems of the switching models. Finally, when a switched system is partially controllable (While some switching models are probably unstabilizable), an on-line feedback control and a cyclic switching strategy are designed such that the overall system is asymptotically stabilizable if all switching models of this uncontrollable subsystems are asymptotically stable. In addition,algorithms for designing switching laws and controls are presented.

Con este fin se muestrearon diferentes fuentes de materias primas líticas y se analizaron materiales arqueológicos provenientes de dos loci de la localidad Bahía Final, cada uno de ellos representativo de un bloque temporal distinto dentro del modelo de uso del espacio y consumo de recursos marinos propuesto para la región. A partir de los análisis realizados se presentan las tendencias generales para el aprovechamiento de rocas a lo largo del tiempo. Los resultados obtenidos sugieren que los patrones de aprovisionamiento y uso de materias primas líticas habrían estado en relación con cambios en los circuitos de movilidad de los grupos cazadores-recolectores que habitaron la zona y con las variaciones geomorfológicas acaecidas en el sector costero bajo estudio.This paper presents an approach to the analysis of provisioning strategies and rock use in the Northern coast of San Matías gulf, Río Negro, Argentina. Our research included the survey of several sources of lithic raw materials and the analysis of lithic assemblages recovered from two Bahía Final archaeological loci, each of which represents a different span of time within the model of space use and marine resource consumption proposed for the region. The general trends in lithic raw material exploitation over time are presented. The results suggest that procurement patterns and lithic raw material use were related both to changes in the mobility circuits of the hunter-gatherers that inhabited the area and to the geomorphological evolution of the marine coast within the study area.

    Full Text Available La estructura de consumo energético, en Venezuela está basada sobre una matriz de combustibles fósiles, ello se debe no solo a la relativa abundancia de estos combustibles por su condición de país petrolero, sino a las políticas de precios subsidiados en el mercado interno. Tal situación ha dificultado la adopción de prácticas eco-eficientes en el país, que mejoren los rendimientos en los sectores de consumo final de mayor intensidad energética, como el sector industrial y el transporte. Sin embargo, frente a las perspectivas del cambio climático y la adhesión del país al protocolo de Kyoto, el Estado venezolano asume el compromiso de diseñar e implementar políticas que estimulen la adopción de prácticas eco-eficientes en los sectores de mayor consumo. Ello requiere de una evaluación de la gestión energética en estos sectores, a los efectos de contribuir con el diseño de estrategias y políticas para mejorar la eficiencia energética. El sector agroalimentario, dentro de los sectores de consumo final antes mencionados, representa un importante componente, por el volumen de su producto industrial y el consumo de materias primas y energía. A tal efecto fue diseñado el proyecto de investigación Gestión Integral (Tecnología, Calidad y Ambiente de la Agroindustria en Venezuela, del cual este estudio forma parte, desarrollado por investigadores de tres universidades nacionales (UCV-ULA-LUZ con apoyo del Fondo Nacional de Ciencia, Tecnología e Investigación (FONACIT. Uno de los objetivos del estudio, fue analizar la estructura energética del sector agroalimentario, así como las iniciativas para incorporar prácticas eco-eficientes en la gestión tecno-ambiental, en una muestra de 129 firmas representativas de las ramas que componen el sector en toda la geografía nacional.

    Full Text Available This paper aims to investigate the continuous contact single roller-to-cam indexing mechanism for optimal designs and capability limits, based on generic transmission and curvature constraint for three dwell periods. First of all, the paper determines the solutions of the problems associated with multiple dwells and then develops optimal designs for three maximum extent dwell periods with equal indexing angles with curvature and transmission constraints. Next, stipulating that the three dwell periods should be equal; iteration is done. This gives optimal designs for three equal maximized dwells with equal indexing periods with curvature and transmission constraints. Final information in the form of capability limits will be very helpful to those who search for various alternative indexing mechanisms for several applications of automatic and packaging industries.

METHODS: Water samples were taken from both the tank input side network water and tank output side tank waters of 200 dwellings with water tanks in Diyarbakir city centre (tank entrance network side water for 200 and tank output side tank water for 200 within the framework of the research study. RESULTS: Coliform bacteria were detected in 35% of the tank entrance side network water samples and in 52.0% percent of the tank output side water samples. Faecal coliform bacteria were not detected in tank entrance side network water samples, but they existed in 2.5% of the tank output side water samples. Free residue chlorine level was found to be over 0.2 ppm in 67% of tank entrance side network water samples and in 35% of the tank output side water samples. Coliform bacteria were detected in 95.5% of the tank entrance side network water samples, of which free residue chlorine level were below 0.2 ppm. Total germ growth was detected in 52.0% of the tank entrance side network water samples and in 67.5% of the tank output side water samples. The most frequently isolated bacteria both in tank entrance side network and tank output side water samples were found to be Bacillus spp. Bacillus type bacteria were found in 48% of tank entrance side network water samples and 57.5% of the tank output side water samples. Filamentous fungi were prevalent in 8% of all the samples examined within the study and the most commonly isolated filamentous fungi were Aspergillus spp (5.5% and Penicillum spp (2.5%.

    Full Text Available Understanding the nature of rail transit dwell time has potential benefits for both the users and the operators. Crowded passenger trains cause longer dwell times and may prevent some passengers from boarding the first available train that arrives. Actual dwell time and the process of passenger alighting and boarding are interdependent through the sequence of train stops and propagated delays. A comprehensive and feasible dwell time simulation model was developed and optimized to address the problems associated with scheduled timetables. The paper introduces the factors that affect dwell time in urban rail transit systems, including train headway, the process and number of passengers alighting and boarding the train, and the inability of train doors to properly close the first time because of overcrowded vehicles. Finally, based on a time-driven micro-simulation system, Shanghai rail transit Line 8 is used as an example to quantify the feasibility of scheduled dwell times for different stations, directions of travel and time periods, and a proposed dwell time during peak hours in several crowded stations is presented according to the simulation results.

    Full Text Available In this article, the evolution of the different systems of transporting and storing submarine oil and its by-products (petroleum gas and natural gas, is dealt with stressing the importance of the use of concrete boats. Due to the high cost of oil pipelines, we have passed from tanks built on land to prestressed concrete tanks which can be berthed at great depths or anchored to the bottom to keep them afloat, it being possible to unmoor them for transferring them. Transporting and storing liquated gas leads US to see the advantages of prestressed concrete over steel, as the latter becomes brittle at low temperatures, whereas the former's strength increases. The different forms and possible sections are analyzed, stressing the great importance of the solution of the double concrete hull with pearlite insulation. Finally, a study is made of «light concretes », not the classical types used as thermal and acoustic insulation, but the semi-heavy ones made with expanded clay, high quality sand and P-450 cement, which technique is not yet as developed in Spain at might be wished.En este artículo se trata la evolución de los distintos sistemas de transporte y almacenamiento del petróleo submarino y sus derivados (gas de petróleo y gas natural, resaltando la importancia del uso de barcos de hormigón.

    "To increase the utility of satellite imagery as a source of cheap and current information for planning and managing cities some problems have to be resolved.... One answer is to adopt interpretation methods that use the increased information in a more detailed scene. This paper reports on attempts to measure the morphological patterns in an urban satellite scene and to use these for image interpretation. The interpretation task addressed is the estimation of residential dwelling units from the patterns discernible in high resolution satellite images of cities. The practical results include dwelling estimates that can be aggregated to any geographical unit of analysis, population estimates for cities and a dwelling density surface that can be categorised into any number of residential land-use classes."

    In this work, indoor radon radioactivity concentration levels have been measured in dwellings of Turkey within the frame of the National Radon Monitoring Programme. The (222)Rn concentrations were measured with time-integrating passive nuclear etched track detectors in 7293 dwellings in 153 residential units of 81 provinces, and the radon map of Turkey was prepared. Indoor radon concentrations were distributed in the range of 1-1400 Bq m(-3). The arithmetic mean of the radon gas concentration was found to be 81 Bq m(-3); the geometric mean was 57 Bq m(-3) with a geometric standard deviation of 2.3.

    2016-12-01

    A monitoring campaign was conducted on a sample of more than 3400 dwellings in Brittany, France from 2011 to 2014. The measurements were collected using one passive dosimeter per dwelling over two months during the heating season, according to the NF ISO 11665-8 (2013) standard. Moreover, building characteristics such as the period of construction, construction material, type of foundation, and thermal retrofit were determined using a questionnaire. The final data set consisted of 3233 houses with the measurement results and the questionnaire answers. Multivariate linear regression models were applied to explore the relationships between the indoor radon concentrations and building characteristics, particularly the thermal retrofit. The geometric mean of the indoor radon concentration was 155 Bq m(-3) (with a geometric standard deviation of 3). The houses that had undergone a thermal retrofit had a higher average radon concentration than those that had not, which may have been due to a decrease in air permeability of the building envelope following rehabilitation work that did not systematically include proper management of the ventilation. Other building characteristics, primarily the building material and the foundation type, were associated with the indoor radon concentration. The indoor radon concentrations were higher in older houses built with granite or other stone, with a slab-on-grade foundation and without any ventilation system. Copyright © 2016 Elsevier Ltd.

    Full Text Available The article traces the use and exploitation of race and racial mixing in access to and control of local authorities in the Philippines during Spanish colonial rule, the only level of government available to native people. It analyzes how race determined the position of each individual in the colonial power pyramid—racial categories that were subsequently shaped by and enshrined in law and served to appraise privileges and exceptions. It explores the dichotomous strategies used by native elites in relation to local power during the second half of the nineteenth century. Those Principalías who did not wish to be in local government, or considered them onerous, used racial categories to shirk these responsibilities. By contrast, in the case of Principalías which were interested in occupying these local positions, the elites resorted to a defensive strategy which used the racial system to their advantage to prevent these posts being illegally usurped by Spaniards and Spanish mestizos.En el artículo se rastrean los usos de la raza y el mestizaje en el acceso y control del poder local en Filipinas durante la dominación colonial española. Se analiza cómo la raza determinó la ubicación de cada individuo dentro de la pirámide de poder de la colonia, categorías raciales que moldearon y quedaron solidificadas en la legislación y sirvieron para aquilatar privilegios y excepciones. Se indagan las dicotómicas estrategias desplegadas por las élites nativas en relación al poder local durante la segunda mitad del siglo XIX.

  19. Yet one more dwell time algorithm

    2017-06-01

    The current demand of even more powerful and efficient microprocessors, for e.g. deep learning, has led to an ongoing trend of reducing the feature size of the integrated circuits. These processors are patterned with EUV-lithography which enables 7 nm chips [1]. To produce mirrors which satisfy the needed requirements is a challenging task. Not only increasing requirements on the imaging properties, but also new lens shapes, such as aspheres or lenses with free-form surfaces, require innovative production processes. However, these lenses need new deterministic sub-aperture polishing methods that have been established in the past few years. These polishing methods are characterized, by an empirically determined TIF and local stock removal. Such a deterministic polishing method is ion-beam-figuring (IBF). The beam profile of an ion beam is adjusted to a nearly ideal Gaussian shape by various parameters. With the known removal function, a dwell time profile can be generated for each measured error profile. Such a profile is always generated pixel-accurately to the predetermined error profile, with the aim always of minimizing the existing surface structures up to the cut-off frequency of the tool used [2]. The processing success of a correction-polishing run depends decisively on the accuracy of the previously computed dwell-time profile. So the used algorithm to calculate the dwell time has to accurately reflect the reality. But furthermore the machine operator should have no influence on the dwell-time calculation. Conclusively there mustn't be any parameters which have an influence on the calculation result. And lastly it should take a minimum of machining time to get a minimum of remaining error structures. Unfortunately current dwell time algorithm calculations are divergent, user-dependent, tending to create high processing times and need several parameters to bet set. This paper describes an, realistic, convergent and user independent dwell time algorithm. The

    2013-01-01

    Full Text Available The industrial and economic expansion of China, particularly its rapid urbanization, has resulted in dramatic increased consumption of energy resources and the resulting environmental impacts at local, regional and global levels. Although a national program aimed at the technological development of sustainable buildings with energy saving potential is ongoing, it is also appropriate to consult vernacular architectural tradition. This holds the potential to learn and adapt important cultural ideas developed over time on the art of balancing thermal comfort between climate and limited resources. This paper explores the five different climatic regions into which China is partitioned by the Chinese authorities: severe cold region, cold region, moderate region, hot summer and cold winter region, and hot summer and mild winter region. Analysis of each region covers the climate and its vernacular architecture with a special focus on how sustainability was addressed. Finally, regional climate scenario has been analyzed on the basis of data from Meteonorm V6.1 with special attention paid to passive design strategies.

    Full Text Available Heidegger’s thinking about poetic dwelling and Derrida’s impressions of Freudian estrangement are employed to provide a constitutional analysis of the experience of Japanese architecture, in particular, the Japanese vestibule (genkan. This analysis is supplemented by writings by Japanese architects and poets. The principal elements of Japanese architecture are: (1 ma, and (2 en. Ma is usually translated as ‘interval’ because, like the English word, it applies to both space and time.  However, in Japanese thinking, it is not so much an either/or, but rather a both/and. In other words, Japanese architecture emphasises the temporal aspect of dwelling in a way that Western architectural thinking usually does not. En means ‘joint, edge, the in-between’ as an ambiguous, often asymmetrical spanning of interior and exterior, rather than a demarcation of these regions. Both elements are aimed at producing an experience of temporality and transiency.

    1997-12-31

    This thesis presents a comprehensive study of an energy estimation model that can be used to examine the uncertainty of predicted energy consumption in a dwelling. The variation and uncertainty of input parameters due to the outdoor climate, the building construction and the inhabitants are studied as a basis for further energy evaluations. The occurring variations of energy consumption in nominal similar dwellings are also investigated due to verification of the simulated energy consumption. The main topics are (1) a study of expected variations and uncertainties in both input parameters used in energy consumption calculations and the energy consumption in the dwelling, (2) the development and evaluation of a simplified energy calculation model that considers uncertainties due to the input parameters, (3) an evaluation of the influence of the uncertain parameters on the total variation so that the most important parameters can be identified, and (4) the recommendation of a simplified procedure for treating uncertainties or possible deviations from average conditions. 90 refs., 182 figs., 73 tabs.

    2013-10-01

    Full Text Available On 28 September 1987, the resolution No. 264 On Further Development of Individual Housing in the Republic passed by the Central Committee of the Council of Ministers of the Lithuanian SSR restored the typological group of private dwelling-houses to Lithuanian towns after a break of nearly three decades. Post-modern trends in architecture that prevailed in western countries at that time reached Lithuania in the form of limited spectrum of architectural press. Architectural expression of individual dwelling-houses in Lithuania relied specifically on projects published in foreign magazines (mostly, of Japan, the U.S.A and Western Europe, and later – in the local periodicals. Different features of such analogous architecture were adapted in Lithuanian dwelling-houses in different ways: the spatial structure of the building was used and interpreted in ones, while in the others – only certain specific details, most often published in such professional press. Three groups of individual dwelling-houses were formed: the elite – benchmark-type, typical -adapted and self-taught architecture. They represented examples of architecture, which over the ten-year’s period were built in parallel and intense mode, until finally the economic conditions prevalent in the post-Soviet Lithuania led to the more practical approach to one’s housing, and the style of post-modernism became unfashionable in Lithuania just like in the remaining part of the world.

  7. Output regulation of switched linear multi-agent systems: an agent-dependent average dwell time method

    Jia, Hongwei; Zhao, Jun

    2016-08-01

    The output regulation problem of switched linear multi-agent systems with stabilisable and unstabilisable subsystems is investigated in this paper. A sufficient condition for the solvability of the problem is given. Owing to the characteristics of switched multi-agent systems, even if each agent has its own dwell time, the multi-agent systems, if viewed as an overall switched system, may not have a dwell time. To overcome this difficulty, we present a new approach, called an agent-dependent average dwell time method. Due to the limited information exchange between agents, a distributed dynamic observer network for agents is provided. Further, a distributed dynamic controller based on observer is designed. Finally, simulation results show the effectiveness of the proposed solutions.

    Full Text Available A field study was conducted under "Cerrado" conditions of Brazil, during the dry season of 2000, to evaluate the effect of final irrigation timing on fruit yield, quality, and the use of water in processing tomatoes. Fourteen irrigation cut-off times were employed, 7 days apart, from blossom until harvest. Maximum marketable fruit yield took place when irrigations were cut-off 21 days before harvest (10% of red fruit. Total soluble solids content was linearly reduced at the rate of 0.34 ºBrix per each additional 10 days period of irrigation. Maximum pulp yield was obtained ending irrigation 34 days before harvest (20% of plants holding at least one red fruit. The highest tomato water use efficiency was observed when the last irrigation occurred between 37 and 45 days after blossom, respectively for fruit and pulp yield.O estudo foi realizado nas condições de Cerrado do Brasil, durante o período seco de 2000, para avaliar o efeito da época de paralisação das irrigações na produção, qualidade de frutos e uso de água do tomateiro para processamento. Os tratamentos corresponderam a quatorze épocas de paralisação, espaçadas a cada 7 dias entre o florescimento e a colheita. A maior produtividade de frutos comercializáveis foi obtida quando as irrigações foram suspensas 21 dias antes da colheita (10% dos frutos maduros, enquanto que o maior rendimento de polpa foi alcançado quando as irrigações foram finalizadas 34 dias antes da colheita (20% de plantas com pelo menos um fruto maduro. O teor de sólidos solúveis totais foi reduzido linearmente à taxa de 0,34 ºBrix para cada 10 dias a mais com irrigação. A maior eficiência do uso de água pelo tomateiro foi obtida quando as irrigações foram paralisadas entre 37 e 45 dias após o florescimento, respectivamente para produção de frutos e de polpa.

    DEFF Research Database (Denmark)

    Petersen, Anders

    2009-01-01

    A temporary functional blindness to the second of two spatially separated targets has been identified in numerous studies of temporal visual attention. This effect is known as attentional dwell time and is maximal 200 to 500 ms after presentation of the first target (e.g. Duncan, Ward, Shapiro......, 1994). In most studies of attentional dwell time, two masked targets have been used. Moore et al. (1996) have criticised the masking of the first target when measuring the attentional dwell time, finding a shorter attentional dwell time when the first mask was omitted. In the presented work, the effect...... an impairment of the second target. Hence, the attentional dwell time may be a combined effect arising from attending to both the first target and its mask....

    This project consists of four separate buildings; three terraces comprising 24 dwellings in all, and one four-storey housing block containing 16 flats. The principal objective was to build low-cost housing in which innovative passive solar components could be incorporated at costs acceptable for public housing schemes (maximum 10% of the overall cost). An 'open-loop passive system', developed in Italy about 20 years ago by Barra-Costantini, was chosen. Warm air produced in the solar air panel circulates freely in the storage ceiling, into the rooms and back to the bottom of the air panel by gravity. The system supplies 30% of the net space-heating load. (author)

    2017-04-12

    The progressive anthropization of caves for food resources or economic purposes increases human exposure to pathogens that naturally infect cave-dwelling animals. The presence of wild or domestic animals in the immediate surroundings of caves also may contribute to increasing the risk of emergence of such pathogens. Some zoonotic pathogens are transmitted through direct contact, but many others require arthropod vectors, such as blood-feeding insects. In Africa, hematophagous insects often play a key role in the epidemiology of many pathogens; however, their ecology in cave habitats remains poorly known. During the last decades, several investigations carried out in Afrotropical caves suggested the medical and veterinary importance particularly of insect taxa of the Diptera order. Therefore, the role of some of these insects as vectors of pathogens that infect cave-dwelling vertebrates has been studied. The present review summarizes these findings, brings insights into the diversity of cave-dwelling hematophagous Diptera and their involvement in pathogen transmission, and finally discusses new challenges and future research directions.

    This paper provides calculations of outdoor sound pressure levels (SPLs) at dwellings for 10 wind turbine models, to support Health Canada's Community Noise and Health Study. Manufacturer supplied and measured wind turbine sound power levels were used to calculate outdoor SPL at 1238 dwellings using ISO [(1996). ISO 9613-2-Acoustics] and a Swedish noise propagation method. Both methods yielded statistically equivalent results. The A- and C-weighted results were highly correlated over the 1238 dwellings (Pearson's linear correlation coefficient r > 0.8). Calculated wind turbine SPLs were compared to ambient SPLs from other sources, estimated using guidance documents from the United States and Alberta, Canada.

    The objective of this study was to develop a method for hourly calculation of the operating temperature in order to evaluate summer comfort in dwellings to help improve building design. A simplified method was developed on the basis of the simple hourly method of the standard ISO 13790...... program for thermal simulations of buildings. The results are based on one year simulations of two cases. The cases were based on a low energy dwelling of 196 m². The transmission loss for the building envelope was 3.3 W/m², not including windows and doors. The dwelling was tested in two cases, a case...... for the fulfilment of summer comfort. Thus it is very important to address both opening areas and ventilation rates. The developed simplified method makes it possible to test whether or not a building design for a dwelling will prevent excess of the summer comfort limits set by the building regulations....

    A countrywide survey of radon concentrations in Estonian dwellings was carried out during the period 1998-2001. The survey formed a part of the cooperation program on radiation protection between the Estonian Radiation Protection (Kiirguskeskus) Centre and the Swedish Radiation Protection Authority (SSI). The survey included measurements in a number of dwellings representative for Estonia in detached houses and multifamily buildings (only dwellings on the bottom floor were included in the survey). Altogether, radon concentrations were measured in 515 dwellings, a number large enough to be statistically significant. All measurements were made with alphatrack film detectors of the same type that SSI uses in Sweden. The measurements were made during a 2-3 month period during the winter half-year. Two detectors were used in each dwelling. In Estonia there are 0.17 million dwellings in detached houses and 0.45 million in multi apartment buildings. Of the 1.26 million inhabitants in Estonia. 0.36 million live in detached houses and 0.90 million in multi apartment buildings. Most of the latter were built during the Soviet occupation. Of the dwellings in multifamily buildings 30 % are assumed to be situated on the first floor. The mean radon concentration in dwellings in detached hoses, according to the survey results, is 103 Bq/m{sup 3}, in dwellings on the bottom floor in multi apartment buildings it is 78 Bq/m{sup 3}. In 1% of the dwellings the radon concentration exceeded 400 Bq/m{sup 3}. The highest radon concentration found in the study was 1040 Bq/m{sup 3}. Based on the assumption that the average radon concentration in the dwellings in multi-apartment buildings that are not situated on the bottom floor is 30 Bq/m{sup 3}, and that these dwellings constitute 70% of all dwellings in multi apartment buildings, the mean radon concentration in dwellings in multi apartment buildings is calculated to be 44 Bq/m{sup 3}. The mean value for all Estonia dwellings is calculated

Arising out from previous studies performed for the Petroleum Brazilian Institute, for he Brazilian Ministry of Mines and Energy and for the IAEA, this article considers two sceneries: reference (REF) which considers significant changes, beyond those already consolidated; alternative (ALT), which considers progressive changes in the modal of transportation, in the energy efficiency and a augmented participation of 'clean' energy sources. Both sceneries estimates potential growing of light vehicles fleet, gain of energetic efficiency and a participation of bio fuels and VNG in Brazil, and the rhythm of the implementation. The results show the the difference between the final use of energy by light vehicles in REF (44 MtEP) in 2023 and in ALT (40 MtEP in 2023) can reach almost 10% during the next 20 years.

  9. Uso de dexmedetomidina em anestesiologia

    Directory of Open Access Journals (Sweden)

    Villela Nivaldo Ribeiro

    2003-01-01

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A dexmedetomidina é um novo agonista alfa2-adrenérgico que apresenta relação de seletividade entre os receptores alfa2:alfa1 de 1600:1, com importante ação sedativa e analgésica, bom controle hemodinâmico frente ao estresse e que pode produzir, por si só, anestesia. Este agente tem sido empregado para promover analgesia e sedação no período pós-operatório e nas unidades de tratamento intensivo. Devido à suas propriedades, recentemente, a dexmedetomidina passou a ser utilizada também na sala de operações, como fármaco coadjuvante em anestesia. Assim, este artigo faz uma revisão da literatura com relação ao uso da dexmedetomidina na prática anestésica. CONTEÚDO: São apresentados os principais trabalhos com o emprego da dexmedetomidina em Anestesiologia, seja como medicação pré-anestésica, ou durante o ato anestésico-cirúrgico. O mecanismo de ação dos fármacos alfa2-agonistas e as propriedades farmacocinéticas e farmacodinâmicas da dexmedetomidina também são revistos neste artigo. CONCLUSÕES: O uso da dexmedetomidina como medicação pré-anestésica, durante anestesia, ou no período pós-operatório, promove boa estabilidade hemodinâmica. Há redução do consumo de anestésicos durante a anestesia. Os pacientes sedados com a dexmedetomidina podem ser despertados, quando solicitados, e tornarem-se cooperativos. Mesmo doses elevadas do fármaco não provocam depressão respiratória. Bradicardia é um efeito adverso observado com freqüência, problema amenizado pela administração lenta da droga. Assim, a dexmedetomidina torna-se importante recurso adicional para a prática clínica da Anestesiologia, com possibilidade de uso em diversos tipos de pacientes e procedimentos cirúrgicos.

    The domestic sector consumes almost one quarter of the national electrical energy. In order to reduce in an important manner the power consumption in dwellings there is an integral alternative based on three elements: the bio-climatic design, the saving and efficient use of the energy in equipment and apparatuses, and the use of centralized air conditioning systems. Besides saving the electrical and thermal power consumption, with this scheme, comfort conditions are pretended to be reached in dwellings and, contributing at the same time, to the diminution of polluting emissions.

    Full Text Available The life in subterranean caves always needs a high degree of biological adaptability, due to its unusual ecosystem. The cave dwelling species usually get selected from preadapted biological traits for cave life. The cave dwelling tendencies in frog are very uncommon. Majority of reported cave frogs usually prefer cave for temporary shelter. In India, the biospeleological inventory is still in its primary stage. Till date no serious attempt has been taken to understand the cave dwelling habitat for any frog in India. Inspite of it, in India time to time various reports on natural histories of anurans reveal its cave dwelling tendencies. On the basis of personal observations and available literature in this report I have documented the occurrences and distributions of five cave dwelling frogs of India. Common biological traits from all the established cave frogs, which could be referred as preadapted for cave life, have been discussed. Further, the possible threats and IUCN status of each discussed species has been highlighted.

    2016-03-01

    A national survey on indoor environmental quality covering 567 residences in mainland France was performed during 2003-2005. The measured parameters were temperature, relative humidity, CO2, and the indoor air pollutants: fourteen individual volatile organic compounds (VOC), four aldehydes and particulate matter PM10 and PM2.5. The measured indoor concentrations were analyzed for correlations with the building characteristics: type of dwelling, period of construction, dwelling location, type of ventilation system, building material, attached garage and retrofitting. The median night time air exchange rate (AER) for all dwellings was 0.44 h-1. The night time AER was higher in apartments (median = 0.49 h-1) than in single-family houses (median = 0.41 h-1). Concentration of formaldehyde was approximately 30% higher in dwellings built after 1990 compared with older ones; it was higher in dwellings with mechanical ventilation and in concrete buildings. The VOC concentrations depended on the building characteristics to various extents. The sampling season influenced the majority of the indoor climate parameters and the concentrations of the air pollutants to a higher degree than the building characteristics. Multivariate linear regression models revealed that the indoor-outdoor difference in specific humidity, a proxy for number of occupants and their indoor activities, remained a significant predictor for most gaseous and particulate air pollutants. The other strong predictors were outdoor concentration, smoking, attached garage and AER (in descending order).

    2012-01-01

    Full Text Available Este texto pone en duda la hipótesis según la cual las estrategias de gestión que consideran la subjetividad del trabajador serían esencialmente libertarias. Condiciones históricas son discutidas antes de la llegada del capitalismo en Brasil-Colonia y en Francia del siglo XVIII, donde la subjetividad del trabajador se moviliza instrumentalmente. Las investigaciones de Elton Mayo son vistas como un momento especial en que la psicología industrial conservadora "descubre" la subjetividad. También se discuten, en el contexto de las prácticas de gestión, las reflexiones de Foucault, para quien el ejercicio del poder supone el uso de la libertad. Él examina la teoría del capital humano y la ideología del emprendimiento como nuevas formas de movilización de la subjetividad, en tiempos de crisis de la sociedad de retribución. En este trayecto, se argumenta que la movilización de la subjetividad también tiene un propósito antilibertario.

  5. Methods of radon remediation in Finnish dwellings; Asuntojen radonkorjauksen menetelmaet

    Energy Technology Data Exchange (ETDEWEB)

    Arvela, H.

    1995-12-01

    A study was made of remedial measures taken in dwellings with high indoor radon concentrations and the results obtained. The data regarding the remedial measures taken in 400 dwellings was obtained from a questionnaire study. The mean annual average indoor radon concentration before the remedies was 1.500 Bq/m{sup 3}, the concentration exceeding in nearly every house the action level of 400 Bq/m{sup 3}. After the measures were taken the mean indoor radon concentration was 500 Bq/m{sup 3}. The resulting indoor radon concentration was less than 400 Bq/m{sup 3} in 60 percent of the dwellings. The best results were achieved using sub-slab-suction and radon well. These methods effectively decrease both the flow of radon bearing air from soil into dwellings and the radon concentration of leakage air. Typical reduction rates in radon concentration were 70-95 percent. The action level was achieved in more than 70 percent of the houses. Sealing the entry routes and improvement of the ventilation resulted typically in reduction rates of 10-50 percent. The goal of the report is to give useful information for the house owners, the do-it-yourself-mitigators, the mitigation firms and the local authorities. The report includes practical guidance, price information and examples of remedial measures. (13 refs., 10 figs., 2 tabs.).

  15. Robust linear equation dwell time model compatible with large scale discrete surface error matrix.

    Science.gov (United States)

    Dong, Zhichao; Cheng, Haobo; Tam, Hon-Yuen

    2015-04-01

    The linear equation dwell time model can translate the 2D convolution process of material removal during subaperture polishing into a more intuitional expression, and may provide relatively fast and reliable results. However, the accurate solution of this ill-posed equation is not so easy, and its practicability for a large scale surface error matrix is still limited. This study first solves this ill-posed equation by Tikhonov regularization and the least square QR decomposition (LSQR) method, and automatically determines an optional interval and a typical value for the damped factor of regularization, which are dependent on the peak removal rate of tool influence functions. Then, a constrained LSQR method is presented to increase the robustness of the damped factor, which can provide more consistent dwell time maps than traditional LSQR. Finally, a matrix segmentation and stitching method is used to cope with large scale surface error matrices. Using these proposed methods, the linear equation model becomes more reliable and efficient in practical engineering.

  16. Asynchronous H∞ filtering for linear switched systems with average dwell time

    Science.gov (United States)

    Wang, Bo; Zhang, Hongbin; Wang, Gang; Dang, Chuangyin

    2016-09-01

    This paper is concerned with the H∞ filtering problem for a class of continuous-time linear switched systems with the asynchronous behaviours, where 'asynchronous' means that the switching of the filters to be designed has a lag to the switching of the system modes. By using the Lyapunov-like functions and the average dwell time technique, a sufficient condition is obtained to guarantee the asymptotic stability with a weighted H∞ performance index for the filtering error system. Moreover, the results are formulated in the form of linear matrix inequalities that are numerical feasible. As a result, the filter design problem is solved. Finally, an illustrative numerical example is presented to show the effectiveness of the results.

    Liebig, Phoebe S; Koenig, Teresa; Pynoos, Jon

    2006-01-01

    This article explores the relationship between zoning regulations and co-residential family caregiving in the United States. It first provides an overview of U.S. housing policies, especially zoning. We then describe major changes in family structure and composition in the United States with their implications for caregiving and discuss how multigenerational housing options, particularly accessory dwelling units (ADUs) in single-family homes, can help support family caregiving. After an overview of zoning policies and actions that inhibit ADU production, we document current trends, incorporating information from a small non-random study of ADU activity we conducted in 2004. Finally, we present recommendations for promoting more multigenerational housing as a supplement to other family support programs (e.g., dependent care assistance, family caregiver payments) and as a source of affordable, supportive housing for those families choosing co-residence as their eldercare solution.

    Full Text Available At the end of 19th century, the removal of city walls and introduction of mass transport in European cities provided the opportunity to expand cities in green suburban areas. Colonies of small houses with garden plots and allotment gardens developed during this era thus represent a new type of settlement, where green infrastructure (gardens and allotment dwellings are closely intertwined. The gardens in these settlements were originally based on the notion of subsistence economy, providing food and emergency accommodation in periods of crisis. This paper examines the evolution of allotments and particularly allotment dwellings in Germany and Austria by matching the actual practices of gardeners with the formation of and changes in the legal framework. The legislation and zoning regulations, which were predominantly established after the fact, reveal an ongoing process of negotiation between informal practices and planning authorities.

    OBJECTIVE: To test the hypothesis that quantitative measures of gait unsteadiness are increased in community-dwelling elderly fallers. STUDY DESIGN: Retrospective, case-control study. SETTING: General community. PARTICIPANTS: Thirty-five community-dwelling elderly subjects older than 70 years of age who were capable of ambulating independently for 6 minutes were categorized as fallers (age, 82.2 +/- 4.9 yrs [mean +/- SD]; n = 18) and nonfallers (age, 76.5 +/- 4.0 yrs; n = 17) based on history; 22 young (age, 24.6 +/- 1.9 yrs), healthy subjects also participated as a second reference group. MAIN OUTCOME MEASURES: Stride-to-stride variability (standard deviation and coefficient of variation) of stride time, stance time, swing time, and percent stance time measured during a 6-minute walk. RESULTS: All measures of gait variability were significantly greater in the elderly fallers compared with both the elderly nonfallers and the young subjects (p < .0002). In contrast, walking speed of the elderly fallers was similar to that of the nonfallers. There were little or no differences in the variability measures of the elderly nonfallers compared with the young subjects. CONCLUSIONS: Stride-to-stride temporal variations of gait are relatively unchanged in community-dwelling elderly nonfallers, but are significantly increased in elderly fallers. Quantitative measurement of gait unsteadiness may be useful in assessing fall risk in the elderly.

  4. Dwelling Price Ranking versus Socioeconomic Clustering: Possibility of Imputation

    Full Text Available In order to characterize the socioeconomic profile of various geographic units, it is common practice to use aggregated indices. However, the process of calculating such indices requires a wide variety of variables from various data sources available concurrently. Using a number of administrative databases for 2001 and 2003, this study examines the question of whether dwelling prices in a given locality can serve as a proxy for its socioeconomic level. Based on statistical and geographic criteria, we developed a Dwelling Price Ranking (DPR methodology. Our findings show that the DPR can serve as a good approximation for the socioeconomic cluster (SEC calculated by the Israel Central Bureau of Statistics for years when the required data was available. As opposed to the SEC, the suggested DPR indicator can easily be calculated, thus ensuring a continuum of socioeconomic index series. Both parametric and nonparametric statistical analyses have been carried out in order to examine the additional social, demographic, location, crime and security effects that are exogenous to SEC. Complementary analysis on recently published SEC series for 2006 and 2008 show that our conclusions remain valid. The proposed methodology and the obtained findings may be applicable for different statistical purposes in other countries which possess dwelling transactions data.

    2011-01-01

    The influences of heat treatment and cyclic dwells on the notch fatigue resistance of powder metallurgy disk superalloys were investigated for low solvus high refractory (LSHR) and ME3 disk alloys. Disks were processed to produce material conditions with varied microstructures and associated mechanical properties. Notched specimens were first subjected to baseline dwell fatigue cycles having a dwell at maximum load, as well as tensile, stress relaxation, creep rupture, and dwell fatigue crack growth tests at 704 C. Several material heat treatments displayed a bimodal distribution of fatigue life with the lives varying by two orders-of-magnitude, while others had more consistent fatigue lives. This response was compared to other mechanical properties, in search of correlations. The wide scatter in baseline dwell fatigue life was observed only for material conditions resistant to stress relaxation. For selected materials and conditions, additional tests were then performed with the dwells shifted in part or in total to minimum tensile load. The tests performed with dwells at minimum load exhibited lower fatigue lives than max dwell tests, and also exhibited early crack initiation and a substantial increase in the number of initiation sites. These results could be explained in part by modeling evolution of peak stresses in the notch with continued dwell fatigue cycling. Fatigue-environment interactions were determined to limit life for the fatigue cycles with dwells.

    We report the results of a comprehensive study of indoor air quality in typical temperate zone Australian dwellings. Forty dwellings located over an 800 km2 area in the south-east of Melbourne with a range of ages, materials and structures representative of Australian dwellings were selected. A range of indoor air quality pollutants were sampled both inside and outside for one week each in Winter/Spring 2008 and Summer/Autumn 2009. Information was collected on house characteristics, the surrounding areas and occupant activities during the sampling. Weekly indoor averaged CO2 (536 ± 121 ppm), CO (0.3 ± 0.2 ppm), PM2.5 (8.4 ± 4.0 μg m-3), temperatures (21.2 ± 2.0 °C), water vapour mixing ratios (7.9 ± 1.3 g kg-1), benzene (1.3 ± 1.1 μg m-3), toluene (8.8 ± 7.9 μg m-3) and xylenes (6.2 ± 6.7 μg m-3) varied from 1.1 to approximately three times higher compared to the equivalent outdoors concentrations. Formaldehyde (12.2 ± 4.7 ppb), other carbonyls (7.9 ± 2.6 ppb) and total volatile organic compounds (181.1 ± 89.5 μg m-3) had indoor concentrations of factors between eight and 12 times higher compared to outdoor concentrations. Weekly averaged indoor ozone (0.7 ± 0.7 ppb), NO2 (8.4 ± 3.9 ppb) and PM10 (20.4 ± 8.1 μg m-3) were significantly lower than outdoors. Correlations and factor analysis showed the major influences on this indoor air quality were (a) dwelling age, whereby dwellings constructed in recent decades compared to older buildings were found to have increased concentrations of the highly elevated species formaldehyde, other carbonyls and total volatile organic compounds, and (b) combustion and cooking activities that increased the concentrations of multiple species including CO, CO2, NO2, H2O and particles. The indoor pollutant concentrations from this study were in general comparable with or lower than other Australian or overseas studies.

    Life cycle management (LCM) can be applied to the whole construction process, thus making it possible to improve sustainability indicators and also minimize the environmental loads of the full building life cycle. To illustrate this, a case study has been carried out based on the application of the LCM approach to a typical Spanish Mediterranean house located in Barcelona with a total area of 160 m{sup 2} and a projected 50-year life span, which has been modeled according to the Spanish building technical code (CTE). The aim of this research is to use sustainability indicators in the pre-construction and operation (use and maintenance) phases and also to promote and support the adoption of the LCM within the construction industry. This paper concludes that regarding the significant environmental issue of climate change, there was a total emission of 2.34E03 kg CO{sub 2}-Eq/m{sup 2} per 50 years, of which about 90.5% was during the operation phase (use 88.9% and maintenance 1.7%) and the pre-construction phase account for a total of 9.5%. In terms of this dwelling's environmental loads, the operation phase is the most critical because of the high environmental loads from energy consumption for heating, ventilation and air conditioning (HVAC), lighting, electrical appliances and cooking. Additionally, the findings of this study state that the appropriate combination of building materials, improvement in behaviors and patterns of cultural consumption, and the application of government codes would enhance decision-making in the construction industry. Therefore, there is no doubt that applying LCM to the full building life cycle is very important for reducing environmental loads and thereby improving sustainability indicators. Finally, this research will help develop guidelines based on LCM for the construction industry to assist stakeholders in improving customer patterns during the dwelling life cycle. (author)

    Full Text Available É relatado o caso de paciente epilético que, aos 16 anos de idade, ao fazer uso de difenilhidantoina, apresentou, já nos primeiros dias, sinais de intolerância, com sensação de formigamento das extremidades. Aos 36 anos voltou a fazer uso desse mesmo medicamento e apresentou sintomas de labirintite, tendo crises de tipo rotatório quando inclinava a cabeça para a esquerda ou a movia bruscamente. O tratamento específico para labirintite, orientado por otorrinolaringologista, foi ineficaz e o quadro clínico agravou-se progressivamente. Ao fim de seis meses seu exame psíquico revelava leve torpor, lentificação do raciocínio, incapacidade para o trabalho e depressão reativa, observando-se, do ponto de vista neurológico, discreto desvio da marcha para a esquerda e discreto aumento da base de sustentação. Além disto referia a existência de crises rotatórias e vômitos tão frequentes que nos últimos dois meses precisou ser hospitalizado algumas vezes, para ser hidratado. A suspensão da difenilhidantoina com manutenção exclusiva de fenobarbital (do qual também já vinha fazendo uso, determinou regressão rápida dos sintomas citados. Tal fato permitiu concluir que a labirintite foi provocada pelo uso da difenilhidantoina e deve ser incluida na extensa relação de efeitos colaterais provocados por essa droga.

    Mild cognitive impairment can be considered as an intermediate clinical state between normal cognitive aging and mild dementia. Elderly people with this impairment represent an at-risk group for the development of dementia. The aim of this study was to investigate the prevalence of cognitive impairment in community-dwelling older adults by Mini-Mental State Examination (MMSE) and its relationship with socio-demographic variables. In this analytical-descriptive study, 212 subjects admitted to Hamadan's day care centers were selected through simple random sampling method. To gather the data, MMSE was used as well as a questionnaire containing demographic variables. Data analysis was completed through SPSS-16. The sample consisted of 17.9% male, 59.4% of whom were married. According to the results, 96 cases (45.3%) suffered from mild (MMSE≥22), 110 cases (51.9%) from moderate (11≤MMSE≤21) and 6 cases (2.8%) from severe cognitive disorder (MMSE≤10). As findings revealed, factors such as age (Pv = 0.005, r = -0.491) and schooling (Pv cognitive decline in community-dwelling older adults was of normal range. Hence, familial relations and social support can decrease mental status disorder.

    Although acoustic signals are important for communication in many taxa, signal propagation is affected by environmental properties. Strong environmental constraints should drive call evolution, favoring signals with greater transmission distance and content integrity in a given calling habitat. Yet, few empirical studies have verified this prediction, possibly due to a shortcoming in habitat characterization, which is often too broad. Here we assess the potential impact of environmental constraints on the evolution of advertisement call in four groups of torrent-dwelling frogs in the family Ranidae. We reconstruct the evolution of calling site preferences, both broadly categorized and at a finer scale, onto a phylogenetic tree for 148 species with five markers (∼3600 bp). We test models of evolution for six call traits for 79 species with regard to the reconstructed history of calling site preferences and estimate their ancestral states. We find that in spite of existing morphological constraints, vocalizations of torrent-dwelling species are most probably constrained by the acoustic specificities of torrent habitats and particularly their high level of ambient noise. We also show that a fine-scale characterization of calling sites allows a better perception of the impact of environmental constraints on call evolution.

    Different dimensions of health are intertwined. The purposes of this study were: (1) to investigate the psychological and socioeconomic health status of community-dwelling older adults in Taiwan, and (2) to compare the psychological and socioeconomic health differences among people of different age groups, gender, marital status, and exercise habits. Using stratified random sampling, 384 Taiwanese community-dwelling older adults were recruited for this survey research. Based on the Health Model of Older Adults, seven constructs were measured: (1) psychological health: sleep quality, emotional health, cognitive functioning, and health promotion behaviors; (2) socioeconomic health: social engagement, social support, and financial status. Results showed that most participants were in a good state of psychological and socioeconomic health, except that 38.02% of them suffered from sleep disruptions, and the majority of them were not involved in any social group, nor engaged in any volunteer work. Young-old older adults had better psychological and socioeconomic health than middle-old and old-old older adults. Male older adults had better psychological health than female older adults; however, they had less social engagement and social support than female older adults. Married older adults and exercisers performed better in most of the psychological and socioeconomic health indicators than single/widowed older adults and non-exercisers.

    The aim of this study is to determine the relationship of radon concentrations between dwellings and the schools located in the same regions and to obtain related indoor average radon concentration dwelling-school correction factor for similar locations. The research has been carried out by determining indoor radon concentrations at schools and dwellings located at the same districts in the selected two separate research fields called The Former Adapazari region and The New Adapazari region in the city of Adapazari using a total of 81 Cr-39 passive radon detectors for 75 days. The average radon concentrations have been determined for the dwellings and the schools in 15 districts of the Former Adapazari region as 59.9 Bq m-3 and 57.1 Bq m-3, respectively. The results in 4 districts of the New Adapazari region were 63.5 Bq m-3 for the dwellings and 61.0 Bq m-3 for the schools. Moreover, the annual effective doses were calculated as 1.33 mSv/y and 1.41 mSv/y for the dwellings of Former Adapazari and New Adapazari, respectively. It was seen that the doses received in the dwellings are about four times the doses received in the schools. The indoor radon concentration dwelling-school correction factor was found to be 1.04±0.01 for the research area.

    A study was conducted to determine the processes which govern dwell notch low cycle fatigue (NLCF) behavior of a powder metallurgy (P/M) ME3 disk superalloy. The emphasis was placed on the environmentally driven mechanisms which may embrittle the highly stressed notch surface regions and reduce NLCF life. In conjunction with the environmentally driven notch surface degradation processes, the visco-plastic driven mechanisms which can significantly change the notch root stresses were also considered. Dwell notch low cycle fatigue testing was performed in air and vacuum on a ME3 P/M disk alloy specimens heat treated using either a fast or a slow cooling rate from the solutioning treatment. It was shown that dwells at the minimum stress typically produced a greater life debit than the dwells applied at the maximum stress, especially for the slow cooled heat treatment. Two different environmentally driven failure mechanisms were identified as the root cause of early crack initiation in the min dwell tests. Both of these failure mechanisms produced mostly a transgranular crack initiation failure mode and yet still resulted in low NLCF fatigue lives. The lack of stress relaxation during the min dwell tests produced higher notch root stresses which caused early crack initiation and premature failure when combined with the environmentally driven surface degradation mechanisms. The importance of environmental degradation mechanisms was further highlighted by vacuum dwell NLCF tests which resulted in considerably longer NLCF lives, especially for the min dwell tests.

    Full Text Available The urban heat island (UHI phenomenon and the dependency of buildings on
fossil fuels were the two main issues that formed this dissertation. UHI results in higher air temperatures in dense urban areas compared with their suburbs and rural surroundings. This phenomenon affects human health through thermal discomfort. Furthermore, in the Netherlands, it is estimated that by 2050 the air temperature could be up to 2.3°C warmer as compared to the period of 1981-2010. Besides, the energy consumption of buildings is responsible for 30 to 45% of CO2 emissions. 31% of this consumption belongs to residential buildings. Residential buildings can play a major role in reducing the CO2 emissions caused by fossil fuel consumption.One of the passive architectural design solutions is the courtyard building form. Courtyards have been used for thousands of years in different climates in the world. In hot climates they provide shading, in humid climates they cause a stack effect helping ventilation, in cold climates they break cold winds and protect their microclimate. In temperate climates (such as of the Netherlands, the thermal behaviour of courtyards has been studied less. In this dissertation, low-rise residential courtyard buildings were therefore studied among (and along different urban block types in the Netherlands.As the first step, computer simulations were done as a parametric study for indoor and outdoor thermal comfort. Field measurements were done in actual urban courtyards and in dwellings alongside urban courtyards in the Netherlands (and in a similar temperate climate in the US. A scale model experiment later followed the simulations. Some of these field measurements were used to validate the simulation models. These efforts answered the two main research questions:1 To what extent is a dwelling alongside an urban courtyard more efficient and thermally comfortable than other dwellings?2 To what extent do people have a more comfortable

    Varian has issued two Product Notification Letters warning of known inaccuracies in dwell positions for their GammaMed HDR ring applicator. This inaccuracy was measured for two sets of applicators. Autoexposed radiographs were taken of the HDR source at different dwell positions and analyzed per Varian recommendations using tools within the BrachyVision treatment planning program. Comparison between programmed and actual dwell positions showed the actual positions shifted distally by an average of 0.34 cm (0.17 cm-0.59 cm) across all positions in all rings. A correction method was developed and tested. During planning, the tip of the ring was extrapolated distally beyond its actual position in the patient image set and a proximal offset of the same distance was applied to the dwell positions. A global shift of 0.3 mm corrected all but the most proximal actual dwell position to within +2 mm of the planned position.

    About 40 percent of final energy use in Sweden is used in the housing sector. Heating and hot water use takes 60 percent of that energy use within the sector. Knowledge about heating systems and fuels used in houses and apartment buildings constructed in different time periods is one factor of importance in developing strategies for energy efficiency programmes. Another factor is the behaviour and energy use in households living in dwellings where ownership, tenure and paying responsibilities for heating differs. The report presents an analysis of heating and energy use in the Swedish housing sector in terms of construction period, type of heating systems, fuels and yearly energy use. Concerning apartment buildings all owners with a large share of the housing stock will face needs for reconstruction and repair of heating systems within ten years. In the segment of apartment buildings built in the period 1940-1970 need for reconstruction and more efficient use of energy for heating are identified to be of utmost importance. Normally these buildings are provided heating from a district heating plant, which functions quite well. However, needs for reconstruction are most urgent when it comes to avoid leakage of heat from windows, walls or other parts of the building. A great number of these apartment blocs are owned by public companies. A socio-demographic analysis of households living in different housing segments are calculated and presented. Segregation of households according to income, number of members and generation have direct effects on the amount of energy used has an apparent relation to size of dwellings, form of tenure and ownership of dwellings. Privately owned detached houses are of interest when it comes to heating. A large share of these houses is heated by electricity. Due to increasing prices on electricity house owners install different forms of heating equipments to decrease costs for heating. Many of these house are built in the period 1960

    2003-03-01

    An in-situ ultrasonic guided wave technique is employed for real-time monitoring of crack initiation and evolution during dwell, cyclic fatigue and creep tests of Ti-6242 alloy samples. Ultrasonic signals are acquired continuously during the test at different levels of fatigue load using a high-speed data acquisition system. The initiation time and growth history of primary and multiple secondary cracks are assessed. Localization of the secondary cracks is performed by both the in-situ ultrasonic method and an ultrasonic immersion scanning method which we call "vertical C-scan" (VC scan). The VC scan is developed for imaging small cracks aligned normal to the fatigue sample axis. The fusion of ultrasonic and microradiographic images exhibits good agreement in crack location. Joint use of the three techniques provides location, shape, and size of the secondary cracks.

    Full Text Available This paper reviews briefly the recent history of dwelling design in China. It notes the rapid changes that have taken place since the 1980s and identifies the way contemporary procurement processes leave out the final fit-out and decoration/refurbishment. A range of stakeholders were interviewed, and access was gained to drawings and other technical data that indicated how the secondary processes were carried out. These are largely ungoverned by regulation in the same way necessary for initial design. The key group is the occupants who drive the fit-out and decoration according to personal and cultural requirements, but often with less than perfect understanding of sustainability. The interior design industry has developed rapidly over the same period and was initially lacking in professional knowledge and understanding (something which can still be found. Advice provided to dwelling occupants was based more on appearance than function and efficiency. Over the same period, beneficial modifications to construction processes have been introduced in relation to structural design, and it should be possible to do the same for sustainability-related design issues. The paper advocates: more regulation; better assessment techniques; more information and guidance for home-owners; and a greater focus on energy issues.

    Full Text Available PURPOSE: To determine why community-dwelling women aged 80 years or over were referred for urodynamic evaluation despite their advanced age and which urodynamic diagnosis was made. MATERIALS AND METHODS: One hundred consecutive females (80-93 years were referred to our urodynamics outpatient clinic for evaluation of lower urinary tract symptoms (LUTS between 2005 and 2008. Clinical evaluation comprised of a previous history of LUTS, previous medical history of neurological disease or dementia, pelvic floor dysfunction or prior pelvic surgery. Exclusion criteria were complete retention and severe dementia involving failure to understand simple instructions. Assessed items were results of uroflows (free flow and intubated flow, cystometry and urethral pressure profilometry, and final urodynamic diagnosis. RESULTS: The main complaint evoked by the patients was incontinence (65.0% of which 61.5% was "complicated" and urgency was reported by 70.0%. Interpretable free flow at arrival was very low (44.0%. Prevalence of detrusor overactivity was high, found in 45 patients of whom 16 had detrusor hyperactivity with impaired detrusor contractility. Detrusor overactivity and urgency were strongly associated (p = 0.004. Twenty-five patients had intrinsic sphincteric deficiency alone and 15 detrusor underactivity. CONCLUSION: In this particular community-dwelling with an elderly female population, urodynamics is easily feasible. Incontinence, mainly "complicated" is the more frequent complaint and urgency the more frequent symptom. Urodynamic diagnosis underlines the high incidence of detrusor overactivity as well as impaired detrusor function.

    Inverse planning algorithms for dwell time optimisation in interstitial high-dose-rate (HDR) brachytherapy may produce solutions with large dwell time variations within catheters, which may result in undesirable selective high-dose subvolumes. Extending the dwell time optimisation model with a dwell time modulation restriction (DTMR) that limits dwell time differences between neighboring dwell positions has been suggested to eliminate this problem. DTMRs may additionally reduce the sensitivity for uncertainties in dwell positions that inevitably result from catheter reconstruction errors and afterloader source positioning inaccuracies. This study quantifies the reduction of high-dose subvolumes and the robustness against these uncertainties by applying a DTMR to template-based prostate HDR brachytherapy implants. Three different DTMRs were consecutively applied to a linear dose-based penalty model (LD) and a dose-volume based model (LDV), both obtained from literature. The models were solved with DTMR levels ranging from no restriction to uniform dwell times within catheters in discrete steps. Uncertainties were simulated on clinical cases using in-house developed software, and dose-volume metrics were calculated in each simulation. For the assessment of high-dose subvolumes, the dose homogeneity index (DHI) and the contiguous dose volume histogram were analysed. Robustness was measured by the improvement of the lowest D90% of the planning target volume (PTV) observed in the simulations. For (LD), a DTMR yields an increase in DHI of approximately 30% and reduces the size of the largest high-dose volume by 2-5 cc. However, this comes at a cost of a reduction in D90% of the PTV of 10%, which often implies that it drops below the desired minimum of 100%. For (LDV), none of the DTMRs were able to improve high-dose volume measures. DTMRs were not capable of improving robustness of PTV D90% against uncertainty in dwell positions for both models.

  8. Cooperative action of KIF1A Brownian motors with finite dwell time

    2014-03-01

    We study in detail the cooperative action of small groups of KIF1A motors in its monomeric (single-headed) form within an arrangement relevant to vesicle traffic or membrane tube extraction. It has been recently shown that under these circumstances, the presence of a finite dwell time in the motor cycle contributes to remarkably enhance collective force generation [D. Oriola and J. Casademunt, Phys. Rev. Lett. 111, 048103 (2013), 10.1103/PhysRevLett.111.048103]. We analyze this mechanism in detail by means of a two-state noise-driven ratchet model with hard-core repulsive interactions. We obtain staircase-shaped velocity-force curves and show that motors self-organize in clusters with a nontrivial force distribution that conveys a large part of the load to the central motors. Under heavy loads, large clusters adopt a synchronic mode of totally asymmetric steps. We also find a dramatic increase of the collective efficiency with the number of motors. Finally, we complete the study by addressing different interactions that impose spatial constraints such as rigid coupling and raft-induced confinement. Our results reinforce the hypothesis that the specificity of KIF1A to axonal vesicular transport may be deeply related to its high cooperativity.

    2016-08-01

    In this paper, the problem of switching stabilization for a class of switched nonlinear systems is studied by using average dwell time (ADT) switching, where the subsystems are possibly all unstable. First, a new concept of ADT is given, which is different from the traditional definition of ADT. Based on the new proposed switching signals, a sufficient condition of stabilization for switched nonlinear systems with unstable subsystems is derived. Then, the T-S fuzzy modeling approach is applied to represent the underlying nonlinear system to make the obtained condition easily verified. A novel multiple quadratic Lyapunov function approach is also proposed, by which some conditions are provided in terms of a set of linear matrix inequalities to guarantee the derived T-S fuzzy system to be asymptotically stable. Finally, a numerical example is given to demonstrate the effectiveness of our developed results.

  15. New challenges for energy certification of dwellings - we keep on learning

    In many European countries energy certification of existing dwellings is in an early stage of application. What have we learnt till now? Four main issues arise: how can we make the procedures less expensive and thus more acceptable for society, how can we nevertheless assure quality, how can we further improve the training of experts and finally what to do with the large amount of building and energy data resulting from energy certification?These issues are addressed on the basis of recent (2005-2006) field experience in Belgium. Over 300 energy experts have been trained in the last 2 years, feed-back information was evaluated. In addition the quality of the audits was controlled by several at random on-site check ups. Since the number of audits performed is limited, a quality evaluation is not yet possible, but certainly worthwhile in the near future, also with respect to experiences in other countries.At the same time the cost of the audits was very high and strongly dependant from expert to expert. This was a major drawback for the implementation. Therefore an analysis is on-going in which the balance between cost and accuracy is re-evaluated. Some time-saving tools are discussed.Finally a concept has been developed to process the large amount of valuable data resulting from the energy certification. Data from energy certification can be highly valuable for other studies and government policy programs. This last issue is being developed in the framework of an EIE-project called DATAMINE.

  17. A Fuzzy Logic-Based Approach for Estimation of Dwelling Times of Panama Metro Stations

    Directory of Open Access Journals (Sweden)

    Aranzazu Berbey Alvarez

    2015-04-01

    Full Text Available Passenger flow modeling and station dwelling time estimation are significant elements for railway mass transit planning, but system operators usually have limited information to model the passenger flow. In this paper, an artificial-intelligence technique known as fuzzy logic is applied for the estimation of the elements of the origin-destination matrix and the dwelling time of stations in a railway transport system. The fuzzy inference engine used in the algorithm is based in the principle of maximum entropy. The approach considers passengers’ preferences to assign a level of congestion in each car of the train in function of the properties of the station platforms. This approach is implemented to estimate the passenger flow and dwelling times of the recently opened Line 1 of the Panama Metro. The dwelling times obtained from the simulation are compared to real measurements to validate the approach.

    The wind environment around residential building groups is increasingly concerned, while the dwelling groups as the elementary unit of planning design, its quality of surrounding wind environment will directly affect people’ s life. This study based on the climatic conditions of severe cold regions, selects four dwellings groups with different openings scale and position as the research objects, and then simulates and analyzes the wind speed distribution characteristics of each pattern. Meanwhile, it extracts the wind speed values of one hundred points of each pattern and applies the coefficient of uniformity method to the ecological evaluation. It has been found that grouping pattern of buildings has a dramatic effect on the resulting airflow behavior. Configurations that contain a T⁃shaped central space with small opened side can effectively prevent and contain airflow in the site offer. The interactive influence between layout of dwelling groups and wind environment are explored, so as to provide basis for the planning design of dwelling groups.

  3. Dwelling, house and home: towards a home-led perspective on dementia care.

    2011-08-01

    "Home" is well known from everyday experience, plays a crucial role in all kinds of narratives about human life, but is hardly ever systematically dealt with in the philosophy of medicine and health care. The notion of home is ambiguous, is often used in a metaphorical way, and is closely related to concepts such as house and dwelling. In this paper the phenomenon of home is explored by means of some phenomenological writings of Heidegger, Bollnow, Bachelard and Levinas. Common in their views is that being at home and dwelling mean something more fundamental than an activity we do along with other activities, such as working and travelling. Dwelling, building a house and being at home are fundamental aspects of human existence. Being human is dwelling. While exploring the relevance of this phenomenological perspective for medical theory and practice, the focus is on the care of people suffering from dementia.

    Huang, Chuangxia; Cao, Jie; Cao, Jinde

    2016-10-01

    This paper addresses the exponential stability of switched cellular neural networks by using the mode-dependent average dwell time (MDADT) approach. This method is quite different from the traditional average dwell time (ADT) method in permitting each subsystem to have its own average dwell time. Detailed investigations have been carried out for two cases. One is that all subsystems are stable and the other is that stable subsystems coexist with unstable subsystems. By employing Lyapunov functionals, linear matrix inequalities (LMIs), Jessen-type inequality, Wirtinger-based inequality, reciprocally convex approach, we derived some novel and less conservative conditions on exponential stability of the networks. Comparing to ADT, the proposed MDADT show that the minimal dwell time of each subsystem is smaller and the switched system stabilizes faster. The obtained results extend and improve some existing ones. Moreover, the validness and effectiveness of these results are demonstrated through numerical simulations.

    2017-05-01

    Traditional skywell dwellings in the hot climate regions of China represent an important cultural heritage. Achieving indoor comfort meeting occupants’ expectations, can contribute to the preservation of this unique traditional architecture. Improvement of ventilation and indoor temperatures through natural, sustainable and low impact solutions is an opportunity in achieving building thermal comfort in these traditional dwellings. The existence of skywells provides a good opportunity for the incorporation of downdraught cooling with minor interventions, and thus by avoiding extensive ductwork, saving energy and improving indoor temperatures, it can contribute to the preservation of traditional dwellings. Applicability of downdraught cooling, the history of traditional ventilation solutions, layout and space features of skywell dwelling are discussed and the way of incorporating downdraught cooling as an alternative to air-conditioning into these buildings is investigated.

    Path planning in additive manufacturing (AM) processes has an impact on the thermal histories experienced at discrete locations in simple and complex AM structures. One component of path planning in directed energy deposition is the time required for the laser or heat source to return to a given location to add another layer of material. As structures become larger and more complex, the length of this interlayer dwell time can significantly impact the resulting thermal histories. The impact of varying dwell times between 0 and 40 seconds on the microstructural and mechanical properties of Inconel® 625 and Ti-6Al-4V builds has been characterized. Even though these materials display different microstructures and solid-state phase transformations, the addition of an interlayer dwell generally led to a finer microstructure in both materials that impacted the resulting mechanical properties. With the addition of interlayer dwell times up to 40 seconds in the Inconel® 625 builds, finer secondary dendrite arm spacing values, produced by changes in the thermal history, correspond to increased yield and tensile strengths. These mechanical properties did not appear to change significantly, however, for dwell times greater than 20 seconds in the Inconel® 625 builds, indicating that longer dwell times have a minimal impact. The addition of interlayer dwell times in Ti-6Al-4V builds resulted in a slight decrease in the measured alpha lath widths and a much more noticeable decrease in the width of prior beta grains. In addition, the yield and tensile values continued to increase, nearly reaching the values observed in the rolled plate substrate material with dwell times up to 40 seconds.

  12. Dwell fatigue in two Ti alloys: An integrated crystal plasticity and discrete dislocation study

    It is a well known and important problem in the aircraft engine industry that alloy Ti-6242 shows a significant reduction in fatigue life, termed dwell debit, if a stress dwell is included in the fatigue cycle, whereas Ti-6246 does not; the mechanistic explanation for the differing dwell debit of these alloys has remained elusive for decades. In this work, crystal plasticity modelling has been utilised to extract the thermal activation energies for pinned dislocation escape for both Ti alloys based on independent experimental data. This then allows the markedly different cold creep responses of the two alloys to be captured accurately and demonstrates why the observed near-identical rate sensitivity under non-dwell loading is entirely consistent with the dwell behaviour. The activation energies determined are then utilised within a recently developed thermally-activated discrete dislocation plasticity model to predict the strain rate sensitivities of the two alloys associated with nano-indentation into basal and prism planes. It is shown that Ti-6242 experiences a strong crystallographic orientation-dependent rate sensitivity while Ti-6246 does not which is shown to agree with recently published independent measurements; the dependence of rate sensitivity on indentation slip plane is also well captured. The thermally-activated discrete dislocation plasticity model shows that the incorporation of a stress dwell in fatigue loading leads to remarkable stress redistribution from soft to hard grains in the classical cold dwell fatigue rogue grain combination in alloy Ti-6242, but that no such load shedding occurs in alloy Ti-6246. The key property controlling the behaviour is the time constant of the thermal activation process relative to that of the loading. This work provides the first mechanistic basis to explain why alloy Ti-6242 shows a dwell debit but Ti-6246 does not.

    This report describes the development and preliminary application of an experimental test bed for modeling human behavior in the context of a computer generated environment to analyze the effects of variations in communication modalities, incentives and stressful conditions. In addition to detailing the methodological development of a simulated task environment that provides for electronic monitoring and recording of individual and group behavior, the initial substantive findings from an experimental analysis of distributed interactive communication in simulated space dwelling groups are described. Crews of three members each (male and female) participated in simulated "planetary missions" based upon a synthetic scenario task that required identification, collection, and analysis of geologic specimens with a range of grade values. The results of these preliminary studies showed clearly that cooperative and productive interactions were maintained between individually isolated and distributed individuals communicating and problem-solving effectively in a computer-generated "planetary" environment over extended time intervals without benefit of one another's physical presence. Studies on communication channel constraints confirmed the functional interchangeability between available modalities with the highest degree of interchangeability occurring between Audio and Text modes of communication. The effects of task-related incentives were determined by the conditions under which they were available with Positive Incentives effectively attenuating decrements in performance under stressful time pressure.

    Bacteria living in soil collected from a rice paddy in Fukuoka, Japan, were examined by electron microscopy using a freeze-substitution fixation method. Most of the observed bacteria could be categorized, based on the structure of the cell envelope and overall morphology, into one of five groups: (i) bacterial spore; (ii) Gram-positive type; (iii) Gram-negative type; (iv) Mycobacterium like; and (v) Archaea like. However, a few of the bacteria could not be readily categorized into one of these groups because they had unique cell wall structures, basically resembling those of Gram-negative bacteria, but with the layer corresponding to the peptidoglycan layer in Gram-negative bacteria being extremely thick, like that of the cortex of a bacterial spore. The characteristic morphological features found in many of these uncultured, soil-dwelling cells were the nucleoid being in a condensed state and the cytoplasm being shrunken. We were able to produce similar morphologies in vitro using a Salmonella sp. by culturing under low-temperature, low-nutrient conditions, similar to those found in some natural environments. These unusual morphologies are therefore hypothesized to be characteristic of bacteria in resting or dormant stages.

    Some species of terrestrial lizards in wet-dry tropical climates reduce their body temperatures (T(b)'s) and activity and lower their metabolic rates during the dry season when food and water resources are scarce. However, semiaquatic lizards have access to water and presumably food throughout the year, so it is possible that they will not have the seasonal response seen in terrestrial species. We studied the thermal biology, energetics, and water flux of Varanus indicus, a semiaquatic, mangrove-dwelling varanid in tropical northern Australia. Although V. indicus remained active all year, they reduced their activity in the dry season, but not to the extent of terrestrial varanids. Varanus indicus field metabolic rates decreased by 38% in the dry season mostly as a result of the reduction in activity. Although food and water depletion are the driving forces behind decreases in dry season T(b) selection and energetics for many varanids, V. indicus appears not to be subject to these pressures to the same extent. Thermoregulatory indices indicate that V. indicus actively thermoregulate in the wet and dry seasons, but they do not fully exploit the available thermal resources. These lizards are unusual among varanid lizards in that their midday T(b)'s are relatively low (about 31 degrees C) despite the availability of thermal resources that would allow them to attain substantially higher T(b)'s.

    Background: Falls present a major challenge to active aging, but the relationship between neighborhood factors and falls is poorly understood. This study examined the relationship between fall events and neighborhood factors, including neighborhood social cohesion (sense of belonging, trust, friendliness, and helpfulness) and physical environment (vandalism/graffiti, rubbish, vacant/deserted houses, and perceived safety walking home at night). Methods: Data were analyzed from 9259 participants over four biennial waves (2006-2012) of the Health and Retirement Study (HRS), a nationally representative sample of adults aged 65 and older in the United States. Results: In models adjusting for demographic and health-related covariates, a one-unit increase in neighborhood social cohesion was associated with 4% lower odds of experiencing a single fall (odds ratio (OR): 0.96, 95% confidence interval (CI): 0.93-0.99) and 6% lower odds of experiencing multiple falls (OR: 0.94, 95% CI: 0.90-0.98). A one-unit increase in the physical environment scale was associated with 4% lower odds of experiencing a single fall (OR: 0.96, 95% CI: 0.93-0.99) and with 5% lower odds of experiencing multiple falls (OR: 0.95, 95% CI: 0.91-1.00) in adjusted models. Conclusions: The physical and social neighborhood environment may affect fall risk among community-dwelling older adults. Findings support the ongoing need for evidence-based fall prevention programming in community and clinical settings.

    Full Text Available The complete lack of a sustainable housing market in the cold and rainy context of Valdivia, Southern Chile (39°49’ S, 73°14’ W, draws the need to find an affordable solution for the construction of energy-efficient living spaces. A team of architects undertook the challenge, whilst acknowledging other environmental issues such as the use of recycled materials. Based on research, the greenhouse principle was the focus of the design, as it dealt with prevailing weather conditions in a more proper fashion, by maximising daylight and solar gains during the long, cold winter, and also by allowing small-scale farming all year round, amongst other features. The greenhouse was thought to perform more as an in-between space -in terms of temperature and lightning- to all common zones in a house (e.g., a doorway or a living room, rather than applying to each inhabited space, individually. The architects researched on the above qualities to see whether they applied to the new prototype or not. Both potential overheating -in the short warm season- and glare risks were taken into account, by conducting specific environmental assessments (e.g., natural lighting levels on both physical and virtual models. Keywords: Environmental design, sustainable dwellings, Southern Chile, extreme weather.

    Two models are developed that can estimate derived fuel demands in single-family dwellings, given fixed final demand for space heat by states. One is an extension of a single-period linear programming model of the nation's energy system, the Brookhaven Energy System Optimization Model. In it the demand for single-family space heat is disaggregated by state and type of home-heating system. The other is a multiple-period dynamic programming model of single-family space heat demand, also disaggregated by state and type of system. Preliminary results for each model are presented and compared.

The questionnaire consisted of multiple choice and open ended questions divided into several categories; the adoption and planned adoption of energy saving measures, energy audits, the EPC, building regulations, the energy tax, financial incentives, information tools and socio-economic and dwelling characteristics. Data on motivations for energy use and perceived influences of instruments was also gathered.The questionnaire was used to meet several objectives. To survey the overall effectiveness of the national instruments available to owner occupiers at that time, to compare owner-occupiers who received an EPC to those who did not along several parameters and to compare owner-occupiers who received an energy audit to those who did not along several parameters. Required sample sizes were calculated on the basis of assumptions and several critical components of the questionnaire that required a set response rate to allow statistical comparison (See Appendix 2. Approximately, 30,000 households from the national EPC/energy audit database were sent a link to the questionnaire. The comparison group was created by sending approximately 16,000 members of the Home Owners Association a link to the questionnaire. Following a reminder, a response rate of 17% was received for the EPC/energy audit database and 10% for the Association of Home Owners database. Both descriptive and statistical analysis was conducted on response data. Descriptive analysis focused on whether householders reported an association between the adoption of energy saving measures and instrument use. Pearson’s chi square tests were used to identify whether an association between adopting measures and instruments could be statistically proven.The final research component consisted of a comparative study of several front-runner countries to gather knowledge and examine the instruments associated with success in meeting climate change targets for existing dwellings.

    The National Radon Survey in the Republic of Kalmykia, Russian Federation during 2006-2007 was carried out in a cooperation project between the Swedish Radiation Protection Authority (SSI) and the Russian Institute of Radiation Hygiene (RIRH). In August 2006 SSI, RIRH, federal and local authorities carried out a field study in Kalmykia when radon daughter measurements (equilibrium equivalent radon concentrations in the air) and gamma radiation measurements were made in 103 buildings. Gamma spectrometry measurements were made at several sites. During the visit the cooperating parties devoted some time to the education of local authorities on radon related issues. During three months in the winter season 2006-2007, long term radon trace measurements were made in 525 randomly chosen dwellings in the Republic of Kalmykia. The radon gas activity varied between 3 and 973 Bq/m3, with a mean value of 122 Bq/m3. In 19 of a total of 835 measurement points, the radon activity exceeded the maximum permitted value in Russia of 200 Bq/m3 of EERC. The year-round radon trace measurement were made in 20 houses in Elista, the capital of the Republic of Kalmykia, for comparison with the three-month measurements. The year-round measurements showed some higher values for the radon activity, and a correction factor of 0.85 was applied. Using data on the number of people living in detached houses and apartments, and applying the radon activities measured, the number of new lung cancer cases caused by radon was calculated to be 20 to 40 of the 100 new cases reported annually. The methods of construction of the dwellings in Kalmykia is greatly influenced by the history and culture. Most of them were built after World War II and there are only a few that are newly built because of the poor economic situation and the low population growth rate in the Republic. Most people live in detached houses, one-storied with 3-5 rooms, built directly on the ground or on coquina blocks or on a cast

    To search for measures to describe and relate to accidental falls in community dwelling elderly. A EuroQol EQ-5D questionnaire based on a patient's otoneurological case history provided a general health related quality of life measure, a fall history for the last 3 months and force platform measures for 96 active elderly from a pensioner organization. On average, the elderly experienced 0.3 falls over the preceding three months. A fall was seen to cause a significant deterioration in the quality of life and vertigo and caused fear of falling. The postural instability correlated with falls. Vertigo was present among 42% and was most commonly characterized as episodic and rotatory in factorial analysis items relating to vertigo correlated to falls and balance complaints. Four factors were identified and three of these correlated with falls. Vestibular failure correlated to a fall occurring when a person was rising up; Movement intolerance correlated with falls due to slips and trips, and Near-syncope factor correlated to falls for other reasons. In posturography, the variable measuring critical time describing the memory based "closed loop" control of postural stability carried a risk for accidental fall with an odds ratio of 6. The variable measuring zero crossing velocity showed a high rate of velocity change around the neutral position of stance. Vertigo and poor postural stability were the major reasons for falls in the active elderly. In ageing, postural control is shifted towards open loop control (visual, proprioception, exteroception and vestibular) instead of closed loop control and is a factor that contributes to a fall.

    2014-12-01

    The average radon concentration in Israeli dwellings was assessed by combining the results of a 2006 radon survey in single-family houses with the results of a 2011 radon survey in apartments of multistorey buildings. Both surveys were based on long-term measurements using CR-39 detectors. The survey in multistorey buildings was intended to assess the influence of recent practices in the local building industry on the radon concentrations. These practices include the use of building materials with higher concentrations of the natural radionuclides in the last 20 y than before, as well as the improvement in sealing techniques over that period. Another practice in place since the early 1990 s is the building of a shielded area in every apartment that is known as an RSS (residential secure space). The RSS is a room built from massive concrete walls, floor and ceiling that can be hermetically sealed and is intended to protect its residents from a missile attack. The influence of the above-mentioned features on radon concentrations was estimated by dividing the participating apartments into two groups: apartments in buildings >20 y, built using building materials with low concentrations of the natural radionuclides, regular sealing and without an RSS and apartments in buildings newer than 10 y, built using building materials with higher concentrations of the natural radionuclides, improved sealing and including an RSS. It was found that the average radon concentration in apartments in new buildings was significantly higher than in old buildings and the average radon concentration in single-family houses was significantly higher than in apartments in multistorey buildings. Doses due to indoor radon were estimated on the basis of the updated information included in the 2009 International Commission on Radiological Protection statement on radon.

TIbased electronic devices are attractive as platforms for spintronic applications, and for detection of emergent properties such as Majorana excitations , electron-hole condensates , and the topological magneto-electric effect . Most theoretical proposals envision geometries consisting of a planar TI device integrated with materials of distinctly different physical phases (such as ferromagnets and superconductors). Experimental realization of physics tied to the surface states is a challenge due to the ubiquitous presence of bulk carriers in most TI compounds as well as degradation during device fabrication.

    2016-07-01

    Full Text Available This study focuses on terrestrial reliance of brown trout (Salmo trutta and compared it to the potential prey available (macrozoobenthos and drifting invertebrates in three temperate rivers (Galicia, NW Spain, with special emphasis on variations in terrestrial energy intake through the ontogeny of brown trout. Additionally, we paid particular attention to individual variation of terrestrial resource use within and between age classes. Prey items were grouped in four categories: i aquatic invertebrates; ii imagoes of aquatic invertebrates; iii terrestrial invertebrates; and iv fish prey. Next, energy composition was measured according to dry weight-energy equations for each individual in line with above-mentioned prey categories. Our findings illustrate that terrestrial invertebrates appeared to be scarce in the environment, whereas aquatic food resources were rather abundant and accessible. The use of terrestrial invertebrates tended to increase with age, but with a high degree of inter-individual variation in resource use. In fact, the individual reliance of brown trout on terrestrial invertebrates may vary considerably (between 0% and 76.9%. Besides, the frequency of terrestrial foragers, i.e., individuals with terrestrial invertebrates in their stomachs, increased with age, except in one population which had the maximum value in the age-2 class. The acquisition of terrestrial invertebrates thus appears to be a process strongly dependent upon the actual food availability in the environment, but with a high degree of individual variance in resource use within the same age class. Finally, we discuss that terrestrial invertebrates may largely contribute to cover the energy intake of the species, highlighting the interface between terrestrial and aquatic ecosystems, and thereby the importance of riparian canopy cover as a key factor for food supply of stream-dwelling salmonids species.

    To build an item response theory-based computer adaptive test (CAT) for balance from 3 traditional, fixed-form balance measures: Berg Balance Scale (BBS), Performance-Oriented Mobility Assessment (POMA), and dynamic gait index (DGI); and to examine whether the CAT's psychometric performance exceeded that of individual measures. Secondary analysis combining 2 existing datasets. Community based. Community-dwelling older adults (N=187) who were aged ≥65 years (mean age, 75.2±6.8y, 69% women). Not applicable. The BBS, POMA, and DGI items were compiled into an initial 38-item bank. The Rasch partial credit model was used for final item bank calibration. CAT simulations were conducted to identify the ideal CAT. CAT score accuracy, reliability, floor and ceiling effects, and validity were examined. Floor and ceiling effects and validity of the CAT and individual measures were compared. A 23-item bank met model expectations. A 10-item CAT was selected, showing a very strong association with full item bank scores (r=.97) and good overall reliability (.78). Reliability was better in low- to midbalance ranges as a result of better item targeting to balance ability when compared with the highest balance ranges. No floor effect was noted. The CAT ceiling effect (11.2%) was significantly lower than the POMA (40.1%) and DGI (40.3%) ceiling effects (Pbalance CAT showed excellent accuracy, good overall reliability, and excellent validity compared with individual measures, being the only measure to discriminate between fallers and nonfallers. Prospective examination, particularly in low-functioning older adults and clinical populations with balance deficits, is recommended. Development of an improved CAT based on an expanded item bank containing higher difficulty items is also recommended. Copyright © 2014 American Congress of Rehabilitation Medicine.

  18. Loneliness and all-cause mortality in community-dwelling elderly Singaporeans

    Directory of Open Access Journals (Sweden)

    Angelique Chan

    2015-06-01

    Full Text Available Background: Loneliness is a significant risk factor for mortality among older adults. There are several pathways through which loneliness may operate to increase mortality risk, ranging from biological responses and individual perceptions to social interactions and environmental factors. The proportion of single older (65+ person households has doubled in the last ten years in Singapore. Yet little is understood about the relationship between loneliness, social isolation, and mortality risk among older adults, in Singapore and in Asian contexts in general. Objective: To assess the impact of loneliness and social isolation on the risk of all-cause mortality over a four-year period, controlling for demographic characteristics and health status at baseline. Methods: We used data from a longitudinal survey of community-dwelling Singaporean elderly (N=4,522. Loneliness was assessed using the UCLA three-item loneliness scale. Unadjusted and adjusted Cox proportional hazards regressions were used to estimate mortality risk. Results: In the final adjusted model, living arrangements and social networks outside the household were not associated with all-cause mortality. Loneliness increased the risk of all-cause mortality; those sometimes lonely and mostly lonely were 44.0Š (p=0.005 and 39.0Š (p=0.059 more likely to die compared to those not lonely. Conclusions: Loneliness is associated with higher mortality risks among Singaporean elderly. Mental health among the older population is a major public health concern and community interventions are needed to more efficiently identify, raise awareness of, and increase care for the lonely elderly in the community.

  19. Estimation of CO{sub 2}-emissions from Fires in Dwellings, Schools and Cars in the Nordic Countries

    Energy Technology Data Exchange (ETDEWEB)

    Blomqvist, Per; Simonson McNamee, Margaret

    2009-07-01

    Updated estimates of emissions from fires in dwellings, schools, pre schools and cars are presented for the Nordic countries with the exception of Iceland. The updated emissions are calculated based on fire statistics from 2007 and are compared to results previously presented for 1994 in Sweden. To put the fire emissions data into perspective they are also compared to national estimates of CO{sub 2} emissions as reported by the Swedish EPA to the EU in their National Inventory Report for 2007. The statistical data on fires for Sweden for 2007 is more reliable compared with the data for 1994, which strengthens the updated emission estimate. The major uncertainty in the fire data used for the emission estimate is the interpretation of fire spread which is based on rather crude assumptions. In particular in the case of houses the fire spread area used for the estimate may be an exaggeration thereby giving a possible overestimation of the estimated emissions. Data indicates that the total emission of CO{sub 2} from fires in dwellings (including single family homes, semi-detached houses, summer houses and apartments) in Sweden 2007 is 15,5 kton. Similar values for Denmark (4,1 kton), Finland (6,9 kton) and Norway (6,4 kton). Similar data for school/preschool and car fires indicate that emissions in Sweden are higher than in the other Nordic countries for these categories as well although not by as great an amount. Finally, a comparison between emissions data from other sources of CO{sub 2} and those from fires indicate that emissions of CO{sub 2} from fires are minor compared to most other sources. The previous study based on statistics from 1994 also concluded that fires are a minor source of CO{sub 2} but a relatively significant source of, e.g., particulate matter, VOC, PAH and other large organic species

  20. Ingredients for a Dutch radon action plan, based on a national survey in more than 2500 dwellings.

    A new Euratom directive demands that Member States establish a national action plan for indoor radon. Important requirements are a national reference level for the radon concentration in dwellings, actions to identify dwellings with radon concentrations that might exceed this reference level and the encouragement of appropriate measures to reduce the radon concentrations in dwellings where these are high. This paper provides ingredients and recommendations for a national action plan for radon in dwellings, applicable to the Netherlands. The approach presented here, which may serve as a model for other countries or regions with a comparatively favourable indoor radon situation, is based on the analysis of radon data from a national survey in more than 2500 Dutch dwellings, built since 1930. The annual average activity concentration of radon in dwellings in the Netherlands equals 15.6 ± 0.3 Bq m(-3). The 50th and 95th percentiles were found to be 12.2 and 38.0 Bq m(-3), respectively. In 0.4 per cent of the dwellings we found values above 100 Bq m(-3). Radon concentrations showed correlations with type of dwelling, year of construction, ventilation system, soil type and smoking behaviour of inhabitants. The survey data suggest that it is feasible for the Netherlands to adopt a national reference level for radon in dwellings of 100 Bq m(-3), in line with recommendations by WHO and ICRP. We were able to predict dwellings with a moderate probability for radon concentrations above 100 Bq m(-3) by applying a combination of three selection criteria: location, type of dwelling and manner of ventilation. Of the existing 6.2 million dwellings in the Netherlands (built since 1930), approximately 23-24 thousand are suspected to exceed this level. Some 80% of these are found in the group of naturally ventilated single-family dwellings in either the southern part of Limburg (approx. 13 thousand) or the Meuse-Rhine-Waal river delta (approx. six thousand). This selected

    2005-01-01

    An indoor radon survey was carried out recently in nine cities of Saudi Arabia using nuclear track detectors (NTD)-based passive radon detectors. The survey included Qatif City in the Eastern Province of Saudi Arabia, where 225 detectors were collected back successfully. It was found that the average indoor radon concentration in the dwellings was 22 +/- 15 Bq m(-3). However, one of the dwellings showed an anomalous radon concentration of 535 +/- 23 Bq m(-3). This finding led to a detailed investigation of this dwelling using active and passive techniques. In the active technique, an AlphaGUARD 2000 PRQ radon gas analyser was used. In the passive technique, CR-39 based passive radon detectors were used in all the rooms of the dwelling. Radon exhalation from the wall and the floor was also measured using the can technique. The active measurement confirms the passive one. Before placing the passive radon detectors in all the rooms of the two-storey building, the inhabitant was advised to ventilate his house regularly. The radon concentration in the different rooms was found to vary from 124 to 302 Bq m(-3). Radon exhalation from the floor and the wall of the room with the anomalous radon concentration was found to vary from 0.5 to 0.8 Bq m(-2) h(-1). These low radon exhalation rates suggest that the anomalous radon concentration is most probably due to underground radon diffusion into the dwelling through cracks and joints in the concrete floor.

    To characterize antifungal activities of essential oil of thyme (Thymus vulgaris L.) and pure thymol, as comparative substance, on different mould species isolated from damp dwellings. Fifty samples of wall scrapes were collected from damp dwellings in Zagreb, the capital of Croatia. The members of the following mould genera were recovered from the samples: Aspergillus (44%), Penicillium (18%) Alternaria, Ulocladium, Absidia and Mucor (8%) Cladosporium, Trichoderma and Rhizopus (6%), and Chaetomium (2%). Two strains of Stachybotrys chartarum were isolated from damp dwellings in Slovakia. Antifungal activities of the thyme essential oil, which contains p-cymene (36.5%), thymol (33.0%) and 1,8-cineole (11.3%) as main components, and pure thymol were determined by the dilution method and exposure to vaporous phase of the oil. Minimum inhibitory concentrations (MIC) of both thymol and essential oil were bellow 20 microg ml(-1), except for Mucor spp. (50.20 microg ml(-1)). Thymol exhibited approximately three-times stronger inhibition than essential oil of thyme. The vaporous phase of the thyme essential oil (82 microg l(-1)) in glass chambers strongly suppressed the sporulation of moulds during 60 days of exposure. The thyme essential oil possesses a wide range spectrum of fungicidal activity. The vaporous phase of the oil exhibited long-lasting suppressive activity on moulds from damp dwellings. Essential oil of thyme and thymol could be used for disinfection of mouldy walls in the dwellings in low concentration.

    To study the association of the butyrylcholinesterase K variant (BChE-K) and the plasma BChE activity with mild cognitive impairment (MCI) in Thai community-dwelling patients. One hundred patients diagnosed with MCI and 100 control subjects were recruited from the community-dwelling setting in Bangkok, Thailand. The genotype and allele distributions of the BChE-K were determined by polymerase chain reaction and subsequent DNA sequencing. The BChE activity was measured in plasma according to the Ellman's method. The BChE-K allele frequencies in the Thai community-dwelling patients were in accordance with other ethnics. The BChE-K allele frequency in the control subjects (12%) was higher than that of MCI patients (5.5%), suggesting a protective role of BChE-K for MCI in the Thai community-dwelling patients. The BChE-K homozygotes were significantly associated with lower BChE activity. Our results suggested that the BChE-K may be implicated as a protective factor for MCI in the Thai community-dwelling patients, although a further study with a large sample size is warranted to confirm this.

    针对现有关于侗族传统民居的研究缺乏整体提炼的缺憾,借鉴社会空间理论和实践理论等观点,从象征人类学的视角,系统阐释侗族传统民居的象征内涵。研究发现,侗族传统民居很好地吻合了列斐伏尔的空间演进脉络,是实践基础上的一个表征空间。在侗族传统民居空间意义的形成上,仪式实践扮演着关键的角色。此外,亲属实践、符号实践和秩序实践也有着积极的贡献。综合而言,民居表征的意义最终指向侗族传统文化中自然观、空间观、时间观等多维观念意象,并藉由与民居建造和使用上的宗教-巫术仪式的结合,共同构成了侗族的整体幸福观念表达图式。%In considering of insufficient studies aimed at integrative abstraction for traditional Dong dwelling, the thesis systematically integrated the symbolic connotation of the dwelling from the viewpoint of symbolic anthropology with reference to the theoretic point of social space and practice. The result shows that traditional Dong dwelling fitted well with Lefebvre’s path of spatial evolution, and finally turned into a representational space on the basis of practice. In the forming process of spatial meaning of traditional Dong dwelling, ritual practice played key role. Besides, kinship practice, symbol practice and order practice also had positive contribution. Comprehensively speaking, meaning represented by dwelling ultimately directed to concept of nature, space, time and other multi-dimensional concept image in traditional Dong culture. Through the combination with religious-taboo rituals in building and using of dwelling, the representational meaning of traditional Dong dwelling turned out to be an expression schema of integrative happiness for Dong nationality.

    Full Text Available Con el fin de obtener un diagnóstico del estado actual de conocimiento sobre usos de las palmas en la Amazonia colombiana, se revisaron las principales fuentes de información. Treinta y seis de las 41 etnias indígenas consideradas tuvieron registros de uso. Se registraron 82 especies de palmas usadas (78% de las potenciales y 165 usos distribuidos en ocho categorías; todos los usos se presentan de manera detallada en un catálogo. Las categorías de uso más importantes fueron: utensilios y herramientas, construcción, y alimentación humana. Las diez especies más importantes fueron Bactris gasipaes, Euterpe precatoria, Mauritia flexuosa, Oenocarpus bataua, Attalea maripa, Oenocarpus minor, Astrocaryum chambira, Iriartea deltoidea, Oenocarpus bacaba y Socratea exorrhiza; la mayoría de ellas también han sido registradas como las más importantes en otras partes del Neotrópico. No se encontró ninguna información sobre usos de palmas para varios grupos indígenas, especialmente para las etnias cocama, letuama, piaroa, pisamira y yurí, para las cuales se requieren investigaciones detalladas. Se concluye que a pesar de los vacíos de información, los resultados muestran que las palmas son un recurso muy importante con un gran potencial, y una pieza fundamental para la seguridad alimentaria y el desarrollo sustentable de la Amazonia colombiana. Sugerimos la inclusión de las especies más importantes en programas de manejo y agroforestales, al igual que la implementación y popularización de técnicas de cosecha no destructivas. Recomendamos además que las investigaciones futuras estén enfocadas en desarrollar estrategias de manejo que garanticen el uso sostenible de todas estas especies útiles.

  10. An ELM-Based Approach for Estimating Train Dwell Time in Urban Rail Traffic

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Dwell time estimation plays an important role in the operation of urban rail system. On this specific problem, a range of models based on either polynomial regression or microsimulation have been proposed. However, the generalization performance of polynomial regression models is limited and the accuracy of existing microsimulation models is unstable. In this paper, a new dwell time estimation model based on extreme learning machine (ELM is proposed. The underlying factors that may affect urban rail dwell time are analyzed first. Then, the relationships among different factors are extracted and modeled by ELM neural networks, on basis of which an overall estimation model is proposed. At last, a set of observed data from Beijing subway is used to illustrate the proposed method and verify its overall performance.

    The radon ((222)Rn) activity concentration in 15 dwellings in the Planej village and 10 dwellings in the Gorozhup village has been measured with the aim to complement the national radon survey and to compare the results of two different measurement techniques. The radon concentration has been measured in winter and spring using alpha scintillation cells and in winter, spring and summer by exposing solid-state nuclear track detectors. Both methods gave similar results. Radon concentrations in both villages were similar, ranging from 82 to 432 Bq m(-3); the value of 400 Bq m(-3) was exceeded only in two dwellings. The resulting annual effective doses ranged from 1.78 to 6.40 mSv, with the average values of 3.28 mSv in the Planej village and 3.87 mSv in the Gorozhup village.

    2005-06-01

    Full Text Available The aim of this study in Curaça, Bahia, Northeast Brazil was to explore possible factors associated with the infestation of human dwellings by Triatoma brasiliensis or Triatoma pseudomaculata, two sylvatic triatomine species. We use multiple logistic regression analysis to show how structural features of the peridomiciliary area combine with the number of animals and sociological factors to allow infestation of some dwellings. It is suggested that T. brasiliensis is associated with human activities, while T. pseudomaculata is associated with vegetation and animals. Peridomiciliary farm animals are a strong risk factor for triatomine infestation.

    Two ADI heats transformed at temperatures of 400 and 380 C during temporal range from 2 minutes to 9 hours were studied in details, with emphasis on structure composition and mechanical properties (tensile and fatigue properties were determined). In the case of the shortest dwells the level of mechanical properties is influenced by martensite, which occurs in the structure as a result of subsequent cooling. UTS and yield stress increase slightly with the dwell of isothermal transformation while the values of elongation to fracture as well as of fatigue limit are very closely dependent on the amount of the retained austenite in the microstructure.

    This paper looks at the progressive impact of UK Building Regulations (Part L) on the energy consumption of dwellings with respect to thermal performance of the building envelope. It provides an overview of building legislation,highlighting progressive improvement in building elemental U-values and compliance methods. The focus centres on Building Regulations from 1965 to 2006,at a time when energy conservation has become an integral component of building control due to environmental concerns. Simulation software is used to compare energy consumption for 5 typical UK dwelling types through a series of case studies which illustrate the rate of impact over recent years.

  20. Nordic Standards for measurement of aircraft noise immission in residential areas and noise reduction of dwellings

    Svane, Christian; Plovsing, Birger

    Quantification by measurement of aircraft noise in residential areas and air traffic noise reduction of dwellings suffer from sensibility to the measurement technique used. Around the Copenhagen Airport (200.000 opr./year) 3.500 families have been granted from 50% to 90% of sound insulation costs by the Danish Government. Based on experience from evaluation measurements carried out by the Danish Acoustical Institute, the authors have proposed standardized measurement methods for the outdoor aircraft noise in residential areas and for the noise reduction of dwellings. In 1989 both noise measurement methods were accepted as Nordic Standards (NORDTEST ACOU 074 and 075) by Denmark, Finland, Iceland, Norway and Sweden.

  8. Evaluation of number concentration quantification by single-particle inductively coupled plasma mass spectrometry: microsecond vs. millisecond dwell times.

    Science.gov (United States)

    Abad-Álvaro, Isabel; Peña-Vázquez, Elena; Bolea, Eduardo; Bermejo-Barrera, Pilar; Castillo, Juan R; Laborda, Francisco

    2016-07-01

    The quality of the quantitative information in single-particle inductively coupled plasma mass spectrometry (SP-ICP-MS) depends directly on the number concentration of the nanoparticles in the sample analyzed, which is proportional to the flux of nanoparticles through the plasma. Particle number concentrations must be selected in accordance with the data acquisition frequency, to control the precision from counting statistics and the bias, which is produced by the occurrence of multiple-particle events recorded as single-particle events. With quadrupole mass spectrometers, the frequency of data acquisition is directly controlled by the dwell time. The effect of dwell times from milli- to microseconds (10 ms, 5 ms, 100 μs, and 50 μs) on the quality of the quantitative data has been studied. Working with dwell times in the millisecond range, precision figures about 5 % were achieved, whereas using microsecond dwell times, the suitable fluxes of nanoparticles are higher and precision was reduced down to 1 %; this was independent of the dwell time selected. Moreover, due to the lower occurrence of multiple-nanoparticle events, linear ranges are wider when dwell times equal to or shorter than 100 μs are used. A calculation tool is provided to determine the optimal concentration for any instrument or experimental conditions selected. On the other hand, the use of dwell times in the microsecond range reduces significantly the contribution of the background and/or the presence of dissolved species, in comparison with the use of millisecond dwell times. Although the use of dwell times equal to or shorter than 100 μs offers improved performance working in single-particle mode, the use of conventional dwell times (3-10 ms) should not be discarded, once their limitations are known.

    Full Text Available Switched reluctance motors (SRM are emerging as promising competitors to the vector-controlled induction motor (VCIM drives and permanent magnet (PM motor drives in the variable-speed drive market owing to their robust nature coupled with low cost, simplicity, and capabilityto operate in harsh environments. They are also suitable for nuclear and aerospace applicationsdue to their low inertia and capability to be fed from a dc supply through a simple power converter.The principle of torque production in SRM makes rotor position information mandatory foreffective control of the drive. The torque produced by any particular phase of the SRM isdependent upon the exciting current and the period during which the current is carried by thatphase winding. The conduction period of any particular phase is termed as dwell angle whenit is specified in terms of rotor angular position. In the present work, the SRM operation has beenanalysed in sensor mode and in sensor-less mode, paying special attention to the relationshipbetween dwell angle and output torque ripple. The performance has been studied for differentvalues of dwell angle and the resultant torque profile has been analysed. From the analysis, amethodology has been devised to deduce an appropriate value of dwell angle for minimising thetorque pulsations, given the values of speed and load torque, thus improving the performanceof the SRM drive.

    [Purpose] The Safe Driving Behavior Measure (SDBM) is a self-report measurement tools that assesses the safe-driving behaviors of the elderly. The purpose of this study was to evaluate the test-retest reliability of the SDBM among community-dwelling elderly drivers. [Subjects and Methods] A total of sixty-one community-dwelling elderly were enrolled to investigate the reliability of the SDBM. The SDBM was assessed in two sessions that were conducted three days apart in a quiet and well-organized assessment room. That test-retest reliability of overall scores and three domain scores of the SDBM were statistically evaluated using intraclass correlation coefficients [ICC (2.1)]. Pearson correlation coefficients were used to quantify bivariate associations among the three domains of the SDBM. [Results] The SDBM demonstrated excellent rest-retest reliability for community-dwelling elderly drivers. The Cronbach alpha coefficients of the three domains of person-vehicle (0.979), person-environment (0.944), and person-vehicle-environment (0.971) of the SDBM indicate high internal consistency. [Conclusion] The results of this study suggest that the SDBM is a reliable measure for evaluating the safe- driving of automobiles by community-dwelling elderly, and is adequate for detecting changes in scores in clinical settings.

    2014-08-26

    Inconel 718 is one of the most commonly used superalloys for high temperature applications in gasturbines and aeroengines and is for example used for components such as turbine discs. Turbine discs can be subjected to temperatures up to ∼700 °C towards the outer radius of the disc. During service, the discs might start to develop cracks due to fatigue and long dwell times. Additionally, temperature variations during use can lead to large thermal transients during start-up and shutdown which can lead to overload peaks in the normal dwell time cycle. In this study, tests at 550 °C with an overload prior to the start of each dwell time, have been performed. The aim of the investigation was to get a better understanding of the effects of overloads on the microstructure and crack mechanisms. The microstructure was studied using electron channelling contrast imaging (ECCI). The image analysis toolbox in Matlab was used on cross sections of the cracks to quantify: crack length, branch length, and the number of branches in each crack. It was found that the amount of crack branching increases with an increasing overload and that the branch length decreases with an increasing overload. When the higher overloads were applied, the dwell time effect was almost cancelled out. There is a strong tendency for an increased roughness of the crack path with an increasing crack growth rate.

    Full Text Available To meet the goals established by Directive 2010/31/EU of the European Parliament and of the Council on the energy performance of buildings, the topics of energy efficiency in new and old buildings must be solved. Research and development of new energy solutions and technology are necessary for increasing energy performance of buildings. Three low-energy multi-dwelling buildings have been modelled and analyzed in the presented study. All multi-dwelling houses are made of similar single-family house cells. However, multi-dwelling buildings are of different geometry, flat number and height. DesignBuilder software was used for simulating and determining heating, cooling and electricity demand for buildings. Three different materials (silicate, ceramic and clay concrete blocks as bearing constructions of external walls have been analyzed. To decrease cooling demand for buildings, the possibility of mounting internal or external louvers has been considered. Primary energy savings for multi-dwelling buildings using passive solar measures have been determined.

  6. Minimum Energy Dwelling (MED) workbook: an investigation of techniques and materials for energy conscious design

    Energy Technology Data Exchange (ETDEWEB)

    1977-12-01

    This workbook is based upon information gathered during the design phase of the Minimum Energy Dwelling. The objective of the project, sponsored by the Southern California Gas Co., Department of Energy, and Mission Viejo is to substantially reduce energy use by the incorporation of energy conservation and solar techniques in a single-family detached dwelling. The Project will demonstrate to builders, as well as to the general public, a number of technological innovations that can, at reasonable cost, be included in a dwelling design. The problem facing Southern California Gas Co., along with most other gas utilities, is ever-decreasing amounts of gas at increasing prices. The dwelling designed has approximately 1,150 ft/sup 2/, consistent with current home-building trends. Through the optimum use of energy-conserving appliances, insulation, window and wall shading, exterior coloring, and thermal mass, the yearly energy usage has been reduced by over 50%. Of the remaining 50% of the energy required for heating, cooling, and domestic hot water, the majority is supplied by the solar-energy system. Three hundred twenty square feet (270 effective) of evacuated tube collector are incorporated into the building structure. The hot water provided by the collectors is used to run an absorption chiller for cooling, the domestic hot water, and the heating system. The remaining energy requirements are met by an auxiliary natural gas energy system and a cool-air-economizer cycle.

    This report describes an experiment on the interactions between eutrophication and contaminants in marine sediments. The experiment was performed in 24 continuously flushed glass aquaria within which three sediment-dwelling species were kept in a marine sediment. A filter-feeder, blue mussel, was kept in downstream aquaria. The experiment combined three environmental factors: oxygen availability, the presence or absence of contaminants, the addition of organic matter. The objectives were: (1) to quantify differences in the partitioning of contaminants between sediment, pore water and biota as a result of the treatment, (2) to quantify effects of treatments and interactions between treatments on sediment-dwelling organisms, (3) to identify differences, if any, in the release of contaminants from the sediment as the result of treatments. All three contaminants bio accumulated to higher levels in sediments with increased levels of organic material. Feeding directly or indirectly appeared to be the major route for bioaccumulation of benzo(a)pyrene and mercury. Cadmium was also controlled by the concentration in pore water. Sediment in enriched aquaria released more contaminants than sediment with low organic content. Organic enrichment strongly affected growth in the three sediment-dwelling organisms. Growth was less affected by decreased oxygen availability. The presence of contaminants had little effect on the three sediment-dwelling species at the concentrations used in the experiment. 103 refs., 14 figs., 12 tabs.

    Worldwide, public policies are promoting energy-efficient buildings and accelerating the thermal renovation of existing buildings. The effects of these changes on the indoor air quality (IAQ) in these buildings remain insufficiently understood. In this context, a field study was conducted in 72 energy-efficient dwellings to describe the pollutants known to be associated with health concerns. Measured parameters included the concentrations of 19 volatile organic compounds and aldehydes, nitrogen dioxide, particulate matter (PM2.5 ), radon, temperature and relative humidity. The air stuffiness index and night-time air exchange rate were calculated from the monitored carbon dioxide (CO2 ) concentrations. Indoor and outdoor measurements were performed at each dwelling during one week in each of the two following seasons: heating and non-heating. Moreover, questionnaires were completed by the occupants to characterize the building, equipment, household and occupants' habits. Perspective on our results was provided by previous measurements made in low-energy European dwellings. Statistical comparisons with the French housing stock and a pilot study showed higher concentrations of terpenes, i.e., alpha-pinene and limonene, and hexaldehyde in our study than in previous studies. Alpha-pinene and hexaldehyde are emitted by wood or wood-based products used for the construction, insulation, decoration and furnishings of the dwellings, whereas limonene is more associated with discontinuous sources related to human activities.

    Full Text Available Diurnal grouping in a population of Pyrenean chamois Rupicapra p. pyrenaica was studied by direct observation on the edge of their westernmost distribution. The whole area occupied by a population was surveyed by performing monthly fixed transects over one year. The size of 214 groups ranged from 1 to 54. Both size and composition were quite variable and differed between seasons and habitats. Groups were generally very small (45% of only one animal, median: 2; P75=4, which is characteristic of small and low density forest-dwelling populations. Groups appeared to depend strongly on the annual biological cycle, food distribution and vegetation cover. The spatial segregation between males and females was only evident in the summer, when solitary males mostly occupied the forest and females with kids lived on open pasturelands. All the general patterns on size and composition of the groups occurred in this population.

    Oral health is an important component of general well-being for the elderly. Oral health-related problems include loss of teeth, nonfunctional removable dental prostheses, lesions of the oral mucosa, periodontitis, and root caries. They affect food selection, speaking ability, mastication, social relations, and quality of life. Frailty is a geriatric syndrome that confers vulnerability to negative health-related outcomes. The association between oral health and frailty has not been explored thoroughly. This study sought to identify associations between the presence of some oral health conditions, and frailty status among Mexican community-dwelling elderly. Analysis of baseline data of the Mexican Study of Nutritional and Psychosocial Markers of Frailty, a cohort study carried out in a representative sample of people aged 70 and older residing in one district of Mexico City. Frailty was defined as the presence of three or more of the following five components: weight loss, exhaustion, slowness, weakness, and low physical activity. Oral health variables included self-perception of oral health compared with others of the same age; utilization of dental services during the last year, number of teeth, dental condition (edentate, partially edentate, or completely dentate), utilization and functionality of removable partial or complete dentures, severe periodontitis, self-reported chewing problems and xerostomia. Covariates included were gender, age, years of education, cognitive performance, smoking status, recent falls, hospitalization, number of drugs, and comorbidity. The association between frailty and dental variables was determined performing a multivariate logistic regression analysis. Final models were adjusted by socio-demographic and health factors Of the 838 participants examined, 699 had the information needed to establish the criteria for diagnosis of frailty.

We therefore examined the relationship between weather and physical activity in a cohort of older community-dwelling people. METHODS: We analysed prospectively collected cross-sectional activity data from community-dwelling people aged 65 and over in the Physical Activity Cohort Scotland. We correlated seven day triaxial accelerometry data with daily weather data (temperature, day length, sunshine, snow, rain, and a series of potential effect modifiers were tested in mixed models: environmental variables (urban vs rural dwelling, percentage of green space, psychological variables (anxiety, depression, perceived behavioural control, social variables (number of close contacts and health status measured using the SF-36 questionnaire. RESULTS: 547 participants, mean age 78.5 years, were included in this analysis. Higher minimum daily temperature and longer day length were associated with higher activity levels; these associations remained robust to adjustment for other significant associates of activity: age, perceived behavioural control, number of social contacts and physical function. Of the potential effect modifier variables, only urban vs rural dwelling and the SF-36 measure of social functioning enhanced the association between day length and activity; no variable modified the association between minimum temperature and activity. CONCLUSIONS: In older community dwelling people, minimum temperature and day length were associated with objectively measured activity. There was little evidence for moderation of these associations through potentially modifiable health, environmental, social or psychological variables.

    This research was done to demonstrate the usefulness of the local structural geology characteristics to predict indoor radon concentrations. The presence of geologic faults near dwellings increases the vulnerability of the dwellings to elevated indoor radon by providing favorable pathways from the source uranium-rich bedrock units to the surface. Kruskal-Wallis one-way analyses of variance by ranks were used to determine the distance where faults have statistically significant influence on indoor radon concentrations. The great-circle distance between the 640 spatially referenced basement radon concentration measurements and the nearest fault was calculated using the Haversine formula and the spherical law of cosines. It was shown that dwellings located less than 150 m from a major fault had a higher radon potential. The 150 m threshold was determined using Kruskal-Wallis ANOVA on: (1) all the basement radon measurements dataset and; (2) the basement radon measurements located on uranium-rich bedrock units only. The results indicated that 22.8% of the dwellings located less than 150 m from a fault exceeded the Canadian radon guideline of 200 Bq/m(3) when using all the basement radon measurements dataset. This percentage fell to 15.2% for the dwellings located between 150 m and 700 m from a fault. When using only the basement radon measurements located on uranium-rich bedrock units, these percentages were 30.7% (0-150 m) and 17.5% (150 m-700 m). The assessment and management of risk can be improved where structural geology characteristics base maps are available by using this proxy indicator.

    The objective of the study was to assess the actual ventilation and indoor air quality in the Finnish building stock (dwellings and day-care centers) with special reference to the existing guideline values. Furthermore, the objective was to evaluate the occurrence of symptoms and perceptions among occupants (adult residents, children, workers) in relation to ventilation system, ventilation rate and dampness. The measurements of ventilation and indoor air quality in the dwellings and day-care centers included ventilation rate, CO{sub 2} concentration, and temperature and humidity. Self- and parent-administered questionnaires were distributed to the occupants inquiring their personal characteristics, occurrence of symptoms of interest, perceived indoor air quality and details of their home and work environments. Airflows and air change rates varied remarkably both in the dwellings and day-care centers. In the majority of the dwellings and day-care centers, the Finnish guideline values of ventilation rates were not achieved. No consistent associations were observed between the magnitude of mechanical ventilation rates and the occurrence of eye, respiratory, skin and general symptoms, that is, symptoms of sick building syndrome (SBS) among the day-care workers. The results indicate that there is much room for improvement in the ventilation and indoor air quality of Finnish dwellings and day-care centers. The control of ventilation, temperature and humidity and the prevention of water damage are important issues on which to concentrate in the future. There is need to improve the quality in all phases of construction: design, installation, adjustment, operation, and maintenance

    Full Text Available Introduction. Falls are frequent in older adults and may have serious consequences but awareness of fall-risk is often low. A questionnaire might raise awareness of fall-risk; therefore we set out to construct and test such a questionnaire. Methods. Fall-risk factors and their odds ratios were extracted from meta-analyses and a questionnaire was devised to cover these risk factors. A formula to estimate the probability of future falls was set up using the extracted odds ratios. The understandability of the questionnaire and discrimination and calibration of the prediction formula were tested in a cohort study with a six-month follow-up. Community-dwelling persons over 60 years were recruited by an e-mail snowball-sampling method. Results and Discussion. We included 134 persons. Response rates for the monthly fall-related follow-up varied between the months and ranged from low 38% to high 90%. The proportion of present risk factors was low. Twenty-five participants reported falls. Discrimination was moderate (AUC: 0.67, 95% CI 0.54 to 0.81. The understandability, with the exception of five questions, was good. The wording of the questions needs to be improved and measures to increase the monthly response rates are needed before test-retest reliability and final predictive value can be assessed.

    Two main targets of European and French energy policies are reduction of energy dependency and greenhouse gas mitigation. Energy conservation is unavoidable in order to reach these two goals.The Building sector is the largest end use in Europe, and also the largest CO{sub 2} emitter (if power plant emissions are included in final energy consumption). It is now well admitted that drastic decrease of buildings energy consumption and CO{sub 2} emissions need an intensive retrofitting of building stock, especially housing.This work evaluates various refurbishment scenarios outlook for 2030 of French dwelling stock: Business As Usual (BaU) or accelerate rates, usual technologies or Best Available Technologies (BATs). Emerging technologies (not yet available but with strong potential) are introduced among 'on the shelf' technologies. Studied scenarios include energy efficiency actions as well as energy substitution. Estimations of technical investment cost of studied scenarios are presented.The calculations are done using the MIeL 'Modeling of the Impact of Energy measures for housing' software, developed by EDF and built following a bottom-up approach.

    In this paper, we review a physiological task that is predominant in preventing humans from falling, but that simultaneously also challenges balance: taking a step. In particular, two variants of this task are presented and compared: the voluntary step versus a step induced by an external and unpredictable perturbation. We show that, while these contribute different information, it is interesting to compare these. Indeed, they both are relevant in a global balance assessment and should be included within this, at the same level as tests usually dispensed in the clinical environment such as posturography. We choose to focus on the community-dwelling elderly population, to discuss means of early detection of risk of falls, in order to prescribe an appropriate prevention. An overview of posture-movement coordination and balance recovery strategies is also provided. Finally, a working hypothesis is suggested on how "compensatory protective" steps are controlled and how their evaluation could bring additional information to the global balance assessment of risk of fall.

    Thermal performance of envelopes and indoor thermal environment were technologically improved for traditional wooden vernacular dwellings of Tujia Minority in Western Hunan, China, on the premise of protecting their conventional styles. Thermal insulation boards and wooden boards were added to the interior side of external walls of vernacular dwellings to form two layers of air cavities, so as to gain excellent thermal performance. The indoor temperature of such dwellings after reconstruction was apparently improved compared with the data before reconstruction both in winter and summer, which verified the feasibility and the effectiveness of the reconstruction technologies proposed.

    Full Text Available Abstract Background Dizziness is a common complaint among older adults and has been linked to a wide range of health conditions, psychological and social characteristics in this population. However a profile of dizziness is still uncertain which hampers clinical decision-making. We therefore sought to explore the relationship between dizziness and a comprehensive range of demographic data, diseases, health and geriatric conditions, and geriatric syndromes in a representative sample of community-dwelling older people. Methods This is a cross-sectional, population-based study derived from FIBRA (Network for the Study of Frailty in Brazilian Elderly Adults, with 391 elderly adults, both men and women, aged 65 years and older. Elderly participants living at home in an urban area were enrolled through a process of random cluster sampling of census regions. The outcome variable was the self-report of dizziness in the last year. Several feelings of dizziness were investigated including vertigo, spinning, light or heavy headedness, floating, fuzziness, giddiness and instability. A multivariate logistic regression analysis was conducted to estimate the adjusted odds ratios and build the probability model for dizziness. Results The complaint of dizziness was reported by 45% of elderly adults, from which 71.6% were women (p=0.004. The multivariate regression analysis revealed that dizziness is associated with depressive symptoms (OR = 2.08; 95% CI 1.29–3.35, perceived fatigue (OR = 1.93; 95% CI 1.21-3.10, recurring falls (OR = 2.01; 95% CI 1.11-3.62 and excessive drowsiness (OR = 1.91; 95% CI 1.11–3.29. The discrimination of the final model was AUC = 0.673 (95% CI 0.619-0.727 (p Conclusions The prevalence of dizziness in community-dwelling elderly adults is substantial. It is associated with other common geriatric conditions usually neglected in elderly adults, such as fatigue and drowsiness, supporting its possible multifactorial manifestation. Our

This was analysed using a data base that was created from the data provided by two Galician corpora: the Tesouro Informático da Lingua Galega (TILG and the Corpus de Referencia do Galego Actual (Corga.The development of this form of the verb valerinto a DM entails, in addition to the requirement that it should work in a way distinct from its own sentence-level syntactic structure, certain contextual factors: the text needs to be in a dialogue format and the style needs to be informal. Moreover, in line with the behaviour of MDs, it may be capable of combining with other sentence-external elements and show a tendency to be isolated from the general structure. This generic definition falls short of a full characterization of its working, since its multiple discourse meanings produces consequences for some aspects of its behaviour, such as its place in discourse and the DM’s question pattern.Finally, our findings are compared with the behaviour described for DMs in two other languages: English OK and Spanish vale. In the light of these comparisons and clear parallellisms in their behaviour, it will be argued that the Galician DM vale has undergone extension in the usage of speakers over the past two decades on account of cross-linguistic pragmatic interference, based on the English formula OK and its Castilian translation, vale.

    This paper investigates the problem of robust exponential H_∞ static output feedback controller design for a class of discrete-time switched linear systems with polytopic-type time-varying parametric uncertainties.The objective is to design a switched static output feedback controller guaranteeing the exponential stability of the resulting closed-loop system with a minimized exponential H_∞ performance under average dwell-time switching scheme.Based on a parameter-dependent discontinuous switched Lyapunov function combined with Finsler's lemma and Dualization lemma,some novel conditions for exponential H_∞ performance analysis are first proposed and in turn the static output feedback controller designs are developed.It is shown that the controller gains can be obtained by solving a set of linear matrix inequalities (LMIs),which are numerically efficient with commercially available software.Finally,a simulation example is provided to illustrate the effectiveness of the proposed approaches.

    2015-12-01

    Full Text Available The use of local natural materials in order to reduce the environmental negative impact of buildings has become common practice in recent years; such buildings are to be found in all regions of the planet. The high level of thermal protection provided by the envelope elements made from natural materials such as straw bale insulation, hemp insulation or sheep wool, and their lack of thermal massiveness require a more complex analysis on their ability to keep interior comfort without accentuated variations. This paper proposes a comparative analysis between different solutions for a residential building located near a Romanian city, Cluj-Napoca. The elements of the building envelope are designed in three alternative solutions, using as substitute to classical solutions (concrete and polystyrene, masonry and polystyrene, straw bales and rammed earth for enclosing elements. For this purpose there are conducted numerical simulations of heat and mass transfer, using a mathematical model that allows the analysis of indoor comfort, by comparing both objective factors (air temperature, operative temperature and relative humidity and subjective factors, which are needed to define interior thermal comfort indices PPD and PMV. Finally, a set of conclusions are presented and future research directions are drawn.

    This paper presents an investigation into solutions for the system design of a centralized DCV system in multi-family dwellings. The design focused on simple and inexpensive solutions. A cost benefit estimate showed that the initial cost of implementing DCV in a system with an efficient heat...... are typically controlled by maintaining the static pressure at a fixed level at a selected point in the main duct. However, sustaining the static pressure at a fixed level at part load leads to throttling of all control components and thereby unnecessary energy consumption. Resetting the static pressure at part...... load reduces throttling and energy can be saved. A static pressure reset strategy was applied to a dwelling-specific DCV system where the airflow varied between three fixed rates. The system performance was evaluated for two diffusers. The annual electricity consumption was reduced by 20% to 30% when...

  13. Stochastic kinetics of a single headed motor protein: dwell time distribution of KIF1A

    CERN Document Server

    Garai, Ashok

    2010-01-01

    KIF1A, a processive single headed kinesin superfamily motor, hydrolyzes Adenosine triphosphate (ATP) to move along a filamentous track called microtubule. The stochastic movement of KIF1A on the track is characterized by an alternating sequence of pause and translocation. The sum of the durations of pause and the following translocation defines the dwell time at the binding site on the microtubule. Using the NOSC model (Nishinari et. al. PRL, {\\bf 95}, 118101 (2005)), which captures the Brownian ratchet mechanism of individual KIF1A along with its biochemical cycle, we systematically derive an analytical expression for the dwell time distribution. In principle, our theoretical prediction can be tested by carrying out single-molecule experiments with adequate spatio-temporal resolution.

    In this paper, repeated measurements of radon progeny concentration in dwellings in the Czech Republic are described. Two distinct data sets are available: one based on present measurements in 170 selected dwellings in the Central Bohemian Pluton with a primary measurement carried out in the 1990s and the other based on 1920 annual measurements in 960 single-family houses in the Czech Republic in 1992 and repeatedly in 1993. The analysis of variance model with random effects is applied to data to evaluate the variability of measurements. The calculated variability attributable to repeated measurements is compared with results from other countries. In epidemiological studies, ignoring the variability of measurements may lead to biased estimates of risk of lung cancer.

    Aging causes various changes in body composition, which are critical implications for health and physical functioning in aging adults. The aim of this study was to explore the body composition outcomes of a qigong intervention among community-dwelling aging adults. This was a quasi-experimental study in which 90 participants were recruited. Forty-eight participants (experimental group) attended a 30-min qigong program 3 times per week for 12 weeks, whereas 42 participants (control group) continued performing their usual daily activities. The experimental group achieved a greater reduction in the fat mass percentage at the posttest, and exhibited increased fat-free mass, lean body mass percentage, and lean body mass to fat mass ratio compared with the controls. No difference between the two groups in body mass index, fat mass, and lean body mass was observed. These results indicated that the qigong intervention showed beneficial outcomes of body composition among community-dwelling aging adults.

    2015-07-01

    This paper investigates the problem of adaptive neural tracking control via output-feedback for a class of switched uncertain nonlinear systems without the measurements of the system states. The unknown control signals are approximated directly by neural networks. A novel adaptive neural control technique for the problem studied is set up by exploiting the average dwell time method and backstepping. A switched filter and different update laws are designed to reduce the conservativeness caused by adoption of a common observer and a common update law for all subsystems. The proposed controllers of subsystems guarantee that all closed-loop signals remain bounded under a class of switching signals with average dwell time, while the output tracking error converges to a small neighborhood of the origin. As an application of the proposed design method, adaptive output feedback neural tracking controllers for a mass-spring-damper system are constructed.

    This paper analyses variables associated with community-dwelling older people's engagement in physical activity (PA). Data were examined using the results from the European ZINCAGE study on 306 community-dwelling Italians aged 65 years and over. The lifestyle questionnaire was used to evaluate the data. Levels of regular/non-regular PA were based on ≥ 1 h of weekly exercise. Logistic regression analysis was used to analyze the predictors of PA. Participants reported the time they had spent per week engaging in PA over the last year. Overall, 56.2% of them engaged in regular physical exercise. PA levels decreased in subjects with probable cognitive decline, depression and high perceived stress levels (p<0.001). Lower age, a lower body mass index (BMI), better health status, absence of depression, being married, were all associated with regular PA. The importance of monitoring PA in the elderly emerged, in particular in those having some certain social-demographic characteristics.

  19. Family and Friend Influence on Urban-Dwelling American Indian Adolescent Girl's Sexual Risk Behavior.

    2016-09-01

    Previous research with American Indian (AI) adolescent sexual risk behavior primarily focused on reservation-dwelling youth despite 70% of AIs living off Native lands. Using grounded theory methodology, I sampled 20 adolescent AI girls via talking circles and interviews to explore the perceptions of AI adolescent girls living in an urban, Midwest area about the influence of family and friends on their sexual behavior. Similar to research with other racial groups, participants cited their family and friends as a major influence. Five unique themes emerged related to family and friend influence. Urban-dwelling AI girls rely on their female family members and peers for information related to sex and receive varying messages from their networks of family and friends, which often overlap. AI youth have unique family groups yet have some similarities to other ethnic groups with regard to family and friend relationships that may allow for enhanced intervention development. © The Author(s) 2015.

    The diet of slope dwelling macrourid fishes in the eastern North Pacific is poorly known. We collected several hundred stomach samples to investigate the feeding habits of Coryphaenoides acrolepis and Albatrossia pectoralis, the two dominant slope dwelling macrourids off the continental United States. Coryphaenoides acrolepis exhibited a pronounced ontogenetic shift in diet. Specimens 15 cm with scavenged food constituting approximately 20% of the weight of total prey and occurring in approximately 20% of fish 21-29 cm. Albatrossia pectoralis consumed primarily midwater fish and squid, and we believe that it feeds in the water column. There were significant differences between the diets of A. pectoralis and C. acrolepis suggesting some degree of niche separation between macrourid species on the continental slope of the eastern North Pacific. Both species are at the top of the food web on the upper continental slope and, because of their abundance, may exert significant pressures on their prey populations.

Considerando a análise de regressão utilizada, apesar de os resultados não serem significativos do ponto de vista estatís- tico, sugerem que, com relação aos contratos de swaps, a flexibilidade das cláusulas é mais relevante na freqüência de uso. De maneira análoga, para os contratos a termo, a flexibi- lidade de proteção parece constituir fator mais relevante. Com relação aos contratos futuros, as flexibilidades de cláu- sula e de proteção surgem com coeficientes diferentes de zero na regressão dando indícios da influência destes sub-tipos de flexibilidade na freqüência de utilização do derivativo. Final- mente, para os contratos de opções, não se observou relacio- namento adequado entre sub-tipos de flexibilidade de pro- duto e o seu grau de utilização. Uma possível causa pode ser a complexidade destes instrumentos que torna menos freqüente sua utilização, mesmo tendo diversas características de flexibilidade.

    In the frame of nationwide radon/thoron monitoring program, indoor radon/thoron and their progeny concentrations have been estimated for 210 dwellings situated in 8 towns (urban) and 9 villages (rural) of Chhattisgarh state of India. The measurement has been made on quarterly integrating cycle for one full year in each dwelling. Twin chamber dosimeter cup with LR-115 Type-II Solid State Nuclear Track Detector was used for the measurement of indoor radon/thoron concentration. The results show that the geometric mean of indoor thoron concentration in urban dwellings varies from 11.57 to 25.88Bqm{sup -3} with an overall geometric mean value of 16.65Bqm{sup -3}, while in rural dwellings it varies from 12.50 to 30.08Bqm{sup -3} with an overall geometric mean value of 19.00Bqm{sup -3}. The potential alpha energy concentration (PAEC) levels of thoron in the urban and rural dwellings are found to be 2.58 and 4.57 mWL, respectively. Similarly, the geometric mean of indoor radon concentrations in urban dwellings is found to vary from 20.20 to 30.13Bqm{sup -3} with an overall geometric mean value of 25.28Bqm{sup -3}, while in rural dwellings it varies from 15.50 to 36.05Bqm{sup -3} with an overall geometric mean value of 27.32Bqm{sup -3}. The PAEC levels of radon in the urban and rural dwellings are found to be 1.50 and 1.87 mWL, respectively. The dose contribution of thoron and progeny in total inhalation dose has been found to be more than 20% in all the surveyed places that show the necessity to pay attention to the presence of thoron and progeny from public health point of view.

    2017-05-05

    Perception of indoor air quality (PIAQ) was evaluated in a nationwide survey of 567 French dwellings, and this survey was combined with measurements of gaseous and particulate matter (PM10 and PM2.5 ) indoor air pollutants and indoor climate parameters. The perception was assessed on a nine-grade scale by both the occupants of the dwellings and the inspectors who performed the measurements. The occupants perceived the air quality in their homes as more pleasant than the inspectors. The inspectors perceived the air quality as more unpleasant in dwellings in which the residents smoked indoors. Significant associations between PIAQ and indoor air pollutant concentrations were observed for both the inspectors and, to a lesser extent, the occupants. Introducing confounding parameters, such as building and personal characteristics, into a multivariate model suppressed most of the observed bivariate correlations and identified the tenure status of the occupants and their occupation as the parameters that most influenced their PIAQ. For the inspectors, perceived air quality was affected by the presence of smokers, the season, the type of ventilation, retrofitting, and the concentrations of acetaldehyde and acrolein. © 2017 John Wiley & Sons A/S.

    We examined the epidemiological associations between serum fructosamine and dyslipidemia indices in community-dwelling adults. Clinical characteristics and lipid profiles were analyzed in 1352 community-dwelling adults. The demographic characteristics and laboratory results were grouped according to the quartiles of serum fructosamine concentrations in all eligible individuals. From the bottom to the top quartile of serum fructosamine, there were graded increases in age, total cholesterol (TC), fasting blood glucose (FBG), total protein (TP), triglyceride (TG), total cholesterol/ high density lipoprotein-cholesterol (TC/HDL-C) and atherogenic index of plasma (AIP). Serum fructosamine was positive correlated with age, TC, FBG, TP, TG, TC/HDL-C and AIP in whole individuals. The positive correlations were then observed in both genders between serum fructosamine and TC, FBG, TP, TG. Two dominant factors were identified by principal component analysis. Logistic regression analysis showed that the two factors were associated with increased serum fructosamine with adjustment for gender, age, body mass index (BMI), FBG and TP. The similar results were observed in males, but not in females. Dyslipidemia tends to contribute to increased serum fructosamine concentrations in study population, suggesting that elevated serum fructosamine may herald an increased risk of cardiovascular disease among community-dwelling adults, especially in males.

    Full Text Available Sarcopenia, aging muscle mass loss, and function syndromes can lead to decreased quality of life and increased elderly mortality. The availability of various screening methods and operational definitions in different studies has produced different findings of sarcopenia prevalence. The purpose of this study was to discover the prevalence of sarcopenia in Indonesian community-dwelling elderly based on muscle mass measured by bioimpedance analysis, handgrip strength using hand dynamometer, and physical performance based on six minutes walking test with two different cut-off point parameters of sarcopenia, i.e. the cut-off point recommended by Asian Working Group for Sarcopenia (AWGS and the cut-off point based on the reference used in Taiwan elderly population reference due to the lack of references for Indonesian elderly population. A cross-sectional study was conducted to 229 participants (71 men and 158 women from the community-dwelling elderly population between August and December 2014 in Bandung and Jatinangor. The results of the study showed that the sarcopenia prevalence in this study based on AWGS was 9.1% (7.4% in men and 1.7% in women while the prevalence based on the Taiwan reference revealed a prevalence of 40.6% (20.1% in men and 20.5% in women. This highly different prevalences shows the importance of defining a specific cut-off point for elderly population in community-dwelling Indonesia to get a more accurate sarcopenia prevalence.

  4. Mechanisms of dwell fatigue crack growth in an advanced nickel disc alloy RR1000

    Directory of Open Access Journals (Sweden)

    Yu S.Y.

    2014-01-01

    Full Text Available RR1000 is one of an advanced class of nickel-based superalloys developed for disc applications. Under one hour dwell fatigue loading, complex crack growth behaviour has been observed especially in a coarse grained version of this alloy. At a temperature of 700 ∘C in air an increase of nearly two orders of magnitude in crack growth rates compared to baseline fatigue crack growth rates may be seen. However for certain microstructural conditions, cracks can also demonstrate retardation following initial acceleration. When using a direct current potential difference (d.c.p.d technique for monitoring crack growth, a damage zone of a few hundred microns is often measured ahead of a fast growing crack. Advanced characterisation techniques including SEM, ECCI and X-ray tomography have been adopted in the current study to understand the observed damage zone and retardation phenomenon. It is found that damage zones measured by d.c.p.d reflect brittle and non-uniform advance of the crack resulting from continuous dynamic or quasi-dynamic fracture of an oxide intrusion ahead of the crack tip during the dwell period. In contrast, cracking of the oxide intrusion is less frequent or even prevented during dwell periods associated with a retarded and slow growing crack. Crack tip stress relaxation plays an important role in dictating whether or not dynamic cracking of the oxide intrusion can be avoided.

    Full Text Available Internal exposure from inhalation of radon and its progeny is one of the most significant sources of natural radiation exposure of the population. Radon levels and radon equilibrium factor were measured in the dwellings of Al-Kharj, Saudi Arabia using passive technique. Calibrated CR-39 diffusion type radon detectors were used for radon measurements and the method of can and bare is adapted for the measurement of radon equilibrium factor. Passive measurements enable the accumulation of the result over a long period and cover a wide area. The probability of cancer induction and then the expected mortality was calculated based on different approaches. The results show that the overall weighted mean of annual effective dose for Al-Kharj resident is equal to 1.51 ± 0.8 mSv and The average expected mortality for residents in dwellings of Al-Kharj city is ranged from 0.596 ± 0.25 to 0.369 ± 0.15 death per 10,000 persons of ages from 40 to 70 years respectively.

    Residential buildings have continuously improved in energy efficiency, partly as a consequence of the introduction of energy regulations in many countries. Although better thermal properties and systems efficiency have lowered energy consumption for space heating in recent decades, substantial differences in energy consumption in similar dwellings are still being observed. These differences in consumption are thought to be caused by differences in occupancy patterns, by quality of construction and by rebound effects. This research addresses the effect of energy performance regulations and occupant behavior on energy consumption for space and water heating in dwellings built after the introduction of the energy performance regulations in the Netherlands. The results of this research show that improving the energy efficiency of buildings alone is not enough to decrease that energy consumption. The large differences found in the use of dwellings indicate that, especially in energy efficient houses, occupant behavior provides an opportunity for further reductions in the energy consumption for space heating which could boost the efforts to conserve energy worldwide.

    Numerous studies have reported the relationship between sleep duration and obesity in elderly adults; however, little is known about the relationship of sleep duration and sarcopenia. We examined the relationship of sleep duration with obesity and sarcopenia in community-dwelling older adults. A total of 488 community-dwelling adults (224 men and 264 women) aged ≥65 years were included in the analysis. Self-reported sleep duration and anthropometric data were collected. Skeletal muscle mass was estimated using the predicted equation from a bioelectrical impedance analysis measurement. Obesity and sarcopenia were defined according to the body mass index and the skeletal muscle mass index, respectively. The association between sleep duration and sarcopenia exhibited a U shape in older adults. Compared to adults with 6-8 h of sleep, adults with adults with ≥8 h of sleep had a nearly 2-fold increased risk of sarcopenia (OR: 1.89, 95% CI: 1.01-3.54). Older adults with a sleep duration obesity (OR: 2.15, 95% CI: 1.08-4.30). After gender stratification, the association between obesity and short sleep duration was more robust in women. There were significant associations of sleep duration with either obesity or sarcopenia in community-dwelling older adults. Gender differences in these associations were also observed.

    Full Text Available Objetivo: Determinar los factores que inciden en el tiempo de permanencia de un catéter endovenoso central. Antecedentes: En el paciente con cáncer existen factores propios del estado de inmunocompromiso por el tumor y los efectos colaterales de su tratamiento que aumentan la probabilidad de infección y consecuentemente reducen el tiempo de uso de un catéter. Sujetos: Se integró una cohorte de 306 pacientes con cáncer, con una edad promedio de 59 ± 14,5 años. Intervenciones: Se definió tiempo cero como el día de colocación del catéter. Diariamente se buscaron signos clínicos de infección por catéter, con toma de hemocultivos simultáneos cada 7 días. El desenlace primario fue infección del catéter y el alternativo fin de tratamiento, obstrucción o fallecimiento del paciente. Se comparó el tiempo de permanencia del catéter infectado vs no infectado y su relación con factores de riesgo potenciales. Resultados: Se colocaron 306 catéteres para un total de 4.043 días/catéter. Se infectaron 25 (8,2%. La sobrevida media global fue de 50 días. Se encontró que a mayor tiempo de permanencia, mayor fue la incidencia de infección. En el análisis de sobrevida ajustado, la presencia de infección a distancia (OR = 4,71, IC95% = 1,7-10,1, p = 0,002 fue el factor que mostró una asociación significativa. Conclusiones: El tiempo de vida útil de un catéter es amplia, limitada por la presencia de infección a distancia como factor de riesgo potencial de infección por catéter.Objective: To determine the factors that affect the dwell time of a central venous catheter.

    Knowledge about the need for care of elderly individuals in community dwellings and the factors affecting their needs and support is limited. The aim of this study was to characterize the frailty of a population of elderly individuals living in community dwellings in Sweden in relation to co-morbidity, use of drugs, and risk of severe conditions such as malnutrition, pressure ulcers, and falls. In 2008, 315 elderly individuals living in community dwellings were interviewed and examined as par...

  9. Tandem-ring dwell time ratio in Nigeria: dose comparisons of two loading patterns in standard high-dose-rate brachytherapy planning for cervical cancer

    OpenAIRE

    2015-01-01

    Purpose In high-dose-rate (HDR) brachytherapy (BT), the source dwell times and dwell positions are essential treatment planning parameters. An optimal choice of these factors is fundamental to obtain the desired target coverage with the lowest achievable dose to the organs at risk (OARs). This study evaluates relevant dose parameters in cervix brachytherapy in order to assess existing tandem-ring dwell time ratio used at the first HDR BT center in Nigeria, and compare it with an alternative s...

    Purpose: Determination of source dwell positions of HDR brachytherapy using 2D 729 ion chamber array Methods: Nucletron microselectron HDR and PTW 2D array were used for the study. Different dwell positions were assigned in the HDR machine. Rigid interstitial needles and vaginal applicator were positioned on the 2D array. The 2D array was exposed for this programmed dwell positions. The positional accuracy of the source was analyzed after the irradiation of the 2D array. This was repeated for different dwell positions. Different test plans were transferred from the Oncentra planning system and irradiated with the same applicator position on the 2D array. The results were analyzed using the in house developed excel program. Results: Assigned dwell positions versus corresponding detector response were analyzed. The results show very good agreement with the film measurements. No significant variation found between the planned and measured dwell positions. Average dose response with 2D array between the planned and nearby dwell positions was found to be 0.0804 Gy for vaginal cylinder applicator and 0.1234 Gy for interstitial rigid needles. Standard deviation between the doses for all the measured dwell positions for interstitial rigid needle for 1 cm spaced positions were found to be 0.33 and 0.37 for 2cm spaced dwell positions. For intracavitory vaginal applicator this was found to be 0.21 for 1 cm spaced dwell positions and 0.06 for 2cm spaced dwell positions. Intracavitory test plans reproduced on the 2D array with the same applicator positions shows the ideal dose distribution with the TPS planned. Conclusion: 2D array is a good tool for determining the dwell position of HDR brachytherapy. With the in-house developed program in excel it is easy and accurate. The traditional way with film analysis can be replaced by this method, as the films will be more costly.

    Objective To build an item response theory based computer-adaptive balance test (CAT) from three traditional, fixed-form balance measures: Berg Balance Scale (BBS), Performance-Oriented Mobility Assessment (POMA), and Dynamic Gait Index (DGI); and examine whether CAT psychometric performance exceeded that of individual measures. Design Secondary analysis combining two existing datasets. Setting Community-based. Participants 187 community-dwelling older adults, 65 years or older, mean age 75.2±6.8 years, 69% female. Interventions Not applicable. Main Outcome Measure(s) BBS, POMA, and DGI items were compiled into an initial 38-item bank. Rasch Partial Credit Model was used for final item bank calibration. CAT simulations were conducted to identify the ideal CAT. CAT score accuracy, reliability, floor and ceiling effects, and validity were examined. Floor and ceiling effects and validity of CAT and individual measures were compared. Results A 23-item bank met model expectations. A 10-item CAT was selected, showing very strong association with full item bank scores (r=0.97), and good overall reliability (0.78). Reliability was better in low- to mid-balance ranges due to better item targeting to balance ability, compared with highest balance ranges. No floor effect was noted. CAT ceiling effect (11.2%) was significantly lower than POMA (40.1%) and DGI (40.3%) ceiling effects (pbalance CAT showed excellent accuracy, good overall reliability, and excellent validity compared with individual measures, being the only measure to discriminate between fallers and non-fallers. Prospective examination, particularly in low- functioning elderly and clinical populations with balance deficits, is recommended. Development of an improved CAT based on an expanded item bank containing higher difficulty items is also recommended. PMID:24685388

    Some avian species incorporate aromatic plants to their nests. The "nest protection hypothesis", which posits that volatile secondary compounds contained in these plants may have antiparasite properties, has not received full support. All previous tests of this hypothesis have only considered effects on nest-dwelling ectoparasites, but not on blood-sucking flies. The "drug hypothesis" posits that aromatic plants may stimulate nestling immune system, development, or condition. We tested these hypotheses experimentally in wild blue tits, Cyanistes caeruleus, a species that adds aromatic plants to their nests. We supplemented aromatic plants to half of a sample of nests, while adding grass to the other half of nests. We quantified abundance of two groups of blood-sucking flies (blackflies and biting midges) at two different stages of the reproductive period, and abundance of three nest-dwelling ectoparasites (fleas, mites, and blowflies). Experimental supplementation of aromatic plants reduced abundance of fleas only in nests of yearling females and not in nests of older females. Blackflies and biting midges were both more numerous in nests of yearling females than in nests of older females. Mass of aromatic plants added by females was negatively related with abundance of fleas in control nests but not in experimental nests supplied with aromatic plants. Mass of plants added by females was also positively related with abundance of blackflies during the nestling stage. Finally, aromatic plants did not affect nestling growth or immune responses. We conclude that several factors such as female experience and their ability to add plants to the nest interact to explain effects of aromatic plants on different parasites.

    Depressive symptoms are a leading cause of disability and emotional suffering, particularly in old age. However, evidence on depression and old age in developing countries remains largely ignored. The aim of this study was to examine the relation between health behavior and social conditions with depression among dependent community-dwelling older persons in the Republic of Chile. This is a cross-sectional and inferential study, using nationally representative secondary data. Two models used logistic regression on 640 dependent community-dwelling older persons from all over Chile, who personally answered a depression assessment, excluding those taking antidepressants. The geriatric depression scale (GDS-15) was used as outcome. The first model aims at any kind of depression (GDS 5>). The second aims at severe depression (GDS 10>). As exposure, we used the health behavior and social conditions of the older persons. Socio-demographic and physical conditions were used as adjustment. 44.5% of the older persons presented depressive symptoms. Among them, 11% had severe depression. Logistic regression showed that significant detrimental factors for being depressed in both models were visiting the doctor five times or over because of acute diseases, feeling uncomfortable with their living arrangement, and feeling discriminated. On the other hand, every additional day of physical exercise and living alone had a beneficial and detrimental effect only in model one. Analyses on ways to support older persons living alone and the promotion of physical exercise to avoid depression are needed, along with a deeper understanding of the comfort with their living arrangement. Finally, ways to address the discrimination among older persons should be further explored.

    Full Text Available Abstract Background Besides cognitive decline, Alzheimer's disease (AD leads to physical disability, need for help and permanent institutional care. The trials investigating effects of exercise rehabilitation on physical functioning of home-dwelling older dementia patients are still scarce. The aim of this study is to investigate the effectiveness of intensive exercise rehabilitation lasting for one year on mobility and physical functioning of home-dwelling patients with AD. Methods During years 2008-2010, patients with AD (n = 210 living with their spousal caregiver in community are recruited using central AD registers in Finland, and they are offered exercise rehabilitation lasting for one year. The patients are randomized into three arms: 1 tailored home-based exercise twice weekly 2 group-based exercise twice weekly in rehabilitation center 3 control group with usual care and information of exercise and nutrition. Main outcome measures will be Guralnik's mobility and balance tests and FIM-test to assess physical functioning. Secondary measures will be cognition, neuropsychiatric symptoms according to the Neuropsychiatric Inventory, caregivers' burden, depression and health-related quality of life (RAND-36. Data concerning admissions to institutional care and the use and costs of health and social services will be collected during a two year follow-up. Discussion To our knowledge this is the first large scale trial exploring whether home-dwelling patients with AD will benefit from intense and long-lasting exercise rehabilitation in respect to their mobility and physical functioning. It will also provide data on cost-effectiveness of the intervention. Trial registration ACTRN12608000037303

    Sixty-six semi-volatile organic compounds (SVOCs)-phthalates, polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), one pyrethroid, organochlorine and organophosphorous pesticides, alkylphenols, synthetic musks, tri-n-butylphosphate and triclosan-were measured on PM10 filters collected over 7 days during a nationwide survey of 285 French dwellings, representative of nearly 25 million housing units. Thirty-five compounds were detected in more than half of the dwellings. PAHs, phthalates and triclosan were the major particle-bound SVOCs, with a median concentration greater than 1 ng m-3 for butylbenzyl phthalate (BBP) (median: 1.6 ng m-3), di(2-ethylhexyl) phthalate (DEHP) (46 ng m-3) and di-iso-nonyl phthalate (DiNP) (7.9 ng m-3), and greater than 0.1 ng m-3 for triclosan (114 pg m-3), benzo(a)pyrene (138 pg m-3), benzo(b)fluoranthene (306 pg m-3), benzo(g,h,i)perylene (229 pg m-3), and indeno(1,2,3-c,d)pyrene (178 pg m-3). For most of the SVOCs, higher concentrations were found in the dwellings of smokers and during the heating season. The concentrations of banned SVOCs-namely, PCBs and organochlorine pesticides-were correlated. Permethrin, 4-tert-butylphenol and bisphenol-A showed no correlation with the other SVOCs and seemed to have their own specific sources. Most SVOCs were positively associated with PM10 concentration, suggesting that any factor that raises the mass of indoor airborne particles also increases the exposure to SVOCs through inhalation.

    The hyperalgesic effects of long-term opioid use in community-dwelling adults with chronic pain have not been widely reported. Therefore, the primary aim of this study was to determine the associations between opioid use and heat pain (HP) perception in a sample of community-dwelling adults with chronic pain. The study cohort involved 187 adults (85 opioid and 102 nonopioid) with chronic pain consecutively admitted to an outpatient interdisciplinary pain treatment program. Heat pain perception was assessed using a validated quantitative sensory test method of levels. An effect of opioid use was observed for nonstandardized (P = 0.004) and standardized (P = 0.005) values of HP 5-0.5 in which values of the opioid group were lower (more hyperalgesic) compared with those of the nonopioid group. HP 5-0.5 is a measure of the slope of the line connecting HP 0.5 (HP threshold) and HP 5 (intermediate measure of HP tolerance). In univariable (P = 0.019) and multiple variable (P = 0.003) linear regression analyses (adjusted for age, sex, body mass index, work status, pain diagnosis, pain severity, depression, and pain catastrophizing), opioid use was associated with lower (more hyperalgesic) nonstandardized values of HP 5-0.5. Similarly, in univariable (P = 0.004) and multiple variable (P = 0.011) linear regression analyses (adjusted for work status, pain diagnosis, pain severity, depression, and pain catastrophizing), opioid use was associated with lower standardized values of HP 5-0.5. In this sample of community-dwelling adults, these observations suggest that long-term opioid use was associated with hyperalgesia independent of other clinical factors known to influence HP perception.

    Considering that radon and its progeny exposure is proved to be the main cause of lung cancer among nonsmokers and occupation-time at some commercial establishments and workplaces is equal or even bigger then at domiciles and dwelling, present study has been spread to the constructed closed environment and workplaces of commerce and productive sector. The measurements were performed by the Laboratory of Applied Nuclear Physics of UTFPR in 2009 - 2011 when 120 detectors were installed at domiciles and workplaces of Curitiba, Parana St., Brazil. Experimental setup was based at CR-39 detectors that were installed in diffusion chambers protected with filters. In collaboration with CDTN/CNEN it was performed the calibration of CR-39 detectors at the NIRS in Japan. The exposure time was set to be of 100 days. Alpha particle track development was performed using 6.25M sodium hydroxide (NaOH) solution and ethanol (2%) during 14 hours at 70 deg C. The counting was conducted using an optical microscope. Measured {sup 222}Rn activity levels in dwellings varied between 4.37 Bq/m{sup 3} and 320.82 Bq/m{sup 3} resulting at an average of 46.94 Bq/m{sup 3}. Indoor measurements at workplaces presented the variation of radon activity concentration between 3.08 Bq/m{sup 3} and 67.50 Bq/m{sup 3} resulting at the average of 34.51 Bq/m{sup 3}. Considering the recommendations of the World Health Organization, UNSCEAR and the International Commission on Radiological Protection (ICRP) concerning the radon-in-air concentration inside the dwellings that can reach 200 Bq/m{sup 3} taking into account the occupation-time of 7000 hours/year, obtained results are within normal limits and no mitigation measures have to be performed.

The aim of this survey was to investigate the prevalence of home-dwelling older people at nutritional risk and to identify associated factors using two different nutritional screening instruments as self-report instruments.Methods: This study had a cross-sectional design. A postal questionnaire, including the Norwegian versions of the Nutritional Form for the Elderly (NUFFE-NO and Mini Nutritional Assessment – Short Form (MNA-SF, background variables, and health-related questions was sent to a randomized sample of 6033 home-dwelling older people in southern Norway. A total of 2106 (34.9% subjects were included in the study. Data were analyzed using descriptive statistics and logistic regression analyses.Results: When using the NUFFE-NO and MNA-SF, 426 (22.3% and 258 (13.5% older persons, respectively, were identified to be at nutritional risk. The risk of undernutrition increased with age. Several predictors for being at risk of undernutrition, including chronic disease/handicap and receiving family help, as well as protective factors, including sufficient food intake and having social contacts, were identified.Conclusion: Health professionals must be aware of older people's vulnerability to risk of undernutrition, perform screening, and have a plan for preventing undernutrition. For that purpose, MNA-SF and NUFFE-NO can be suggested for screening older people living at home.Keywords: aged, risk factors, undernutrition, screening

    Since the settlement of S. Miguel Island (Azores), in the XV century, several earthquakes caused important human losses and severe damages on the island. Sete Cidades Volcano area, located in the westernmost part of the island, was attained by strong seismic crises of tectonic and volcanic origin and major events reached a maximum historical intensity of IX (European Macroseismic Scale 1998) in this zone. Aiming to evaluate the impact of a future major earthquakes, a field survey was carried out in ten parishes of Ponta Delgada County, located on the flanks of Sete Cidades volcano and inside it is caldera. A total of 7019 buildings were identified, being 4351 recognized as dwellings. The total number of inhabitants in the studied area is 11429. In this work, dwellings were classified according to their vulnerability to earthquakes (Classes A to F), using the structure types table of the EMS-98, adapted to the types of constructions made in the Azores.

    Since 1976, the US Department of Energy (DOE) has operated one of the largest energy conservation programs in the nation -- the low-income Weatherization Assistance Program. The program strives to increase the energy efficiency of dwellings occupied by low-income persons in order to reduce their energy consumption, lower their fuel bills, increase the comfort of their homes, and safeguard their health. It targets vulnerable groups including the elderly, people with disabilities, and families with children. The most recent national evaluation of the impacts of the Program was completed in 1984 based on energy consumption data for households weatherized in 1981. DOE Program regulations and operations have changed substantially since then: new funding sources, management principles, diagnostic procedures, and weatherization technologies have been incorporated. Many of these new features have been studied in isolation or at a local level; however, no recent evaluation has assessed their combined, nationwide impacts to date or their potential for the future. In 1990, DOE initiated such an evaluation. This evaluation is comprised of three ``impact`` studies (the Single-Family Study, High-Density Multifamily Study, and Fuel-Oil Study) and two ``policy`` studies. Altogether, these five studies will provide a comprehensive national assessment of the Weatherization Assistance Program as it existed in the 1989 Program Year (PY 1989). This report presents the results of the first phase of the Single-Family Study. It evaluates the energy savings and cost effectiveness of the Program as it has been applied to the largest portion of its client base -- low-income households that occupy single-family dwellings, mobile homes, and small (2- to 4-unit) multifamily dwellings. It is based upon a representative national sample that covers the full range of conditions under which the program was implemented in PY 1989.

    Sarcopenia is defined as age-related lean tissue mass (LTM) loss resulting in reduced muscular strength, physical function, and mobility. Up to 33 % of older adults currently are sarcopenic, with likely many more undiagnosed. The purpose of this investigation was to predict sarcopenia status from easily accessible functional measures of community-dwelling older adults. Forty-three community-dwelling older adults (n = 32 females and n = 11 males) participated in the present investigation. Inclusion criteria included ≥65 years of age, mini-mental state examination score ≥24, and no falls within previous 12 months. All subjects completed their appendicular skeletal mass (ASM) assessment via dual-energy X-ray absorptiometry (DXA) and were categorized as either sarcopenic or non-sarcopenic. Physical assessments included 10-m usual walk, hand-grip (HG) strength, 6-min walk, 8-ft up-and-go, 30-s chair stand, 30-s arm curl, and sit-to-stand muscular power. A forward, stepwise multiple regression analysis revealed that age, sex, weight, height, 10-m walk, HG, and sit-to-stand muscular power account for 96.1 % of the variance in ASM. The area under the curve was 0.92 for correctly identifying sarcopenic participants compared to their actual classification. This is the first prediction model used to identify sarcopenia based on parameters of demographic and functional fitness measures in community-dwelling older adults. The ability to accurately identify sarcopenia in older adults is imperative to their quality of life and ability to perform activities of daily living.

    With considerable variation including potential sex-specific differential rate of skeletal muscle loss, identifying modifiable factors for sarcopenia will be pivotal to guide targeted interventions. This study seeks to identify clinical and biological correlates of sarcopenia in community-dwelling older adults, with emphasis on the role of anabolic and catabolic stimuli, and special reference to gender specificity. In this cross-sectional study involving 200 community-dwelling and functionally independent older adults aged ≥50 years, sarcopenia was defined using the Asian Working Group for Sarcopenia criteria. Comorbidities, cognitive and functional performance, physical activity and nutritional status were routinely assessed. Biochemical parameters included haematological indices, lipid panel, vitamin D level, anabolic hormones [insulin-like growth factor-1 (IGF-1), free testosterone (males only)] and catabolic markers [inflammatory markers (interleukin-6, C-reactive protein) and myostatin]. Multiple logistic regression was performed to identify independent predictors for sarcopenia. Age was associated with sarcopenia in both genders. Malnutrition conferred significantly higher odds for sarcopenia in women (OR = 5.71, 95% CI 1.13-28.84.44, p = 0.035) while higher but acceptable range serum triglyceride was protective in men (OR = 0.05, 95% CI 0.00-0.52, p = 0.012). Higher serum myostatin independently associated with higher odds for sarcopenia in men (OR = 1.11, 95% CI 1.00-1.24, p = 0.041). Serum IGF-1 was significantly lower amongst female sarcopenic subjects, with demonstrable trend for protective effect against sarcopenia in multiple regression models, such that each 1 ng/ml increase in IGF-1 was associated with 1% decline in odds of sarcopenia in women (p = 0.095). Our findings support differential pathophysiological mechanisms for sarcopenia that, if corroborated, may have clinical utility in guiding sex-specific targeted

    Radon is a radioactive noble gas derived from the natural decay series of {sup 238}U, {sup 235}U, and {sup 232}Th, which are present in rocks and soils. By diffusion and convection, radon migrates from the rocks and soils to the surface and through fissures, pipes and holes it may enter the dwellings and other buildings. Another important indoor radon source is the building material construction. Therefore, it may accumulate indoor environments with reduced ventilation rates. Radon progeny attach to the aerosol particle in the air. The attached and unattached radon progeny may deposit in the lungs and irradiate to the lung tissue as they decay. Radon has been recognized as a radiation hazard, that causes excess of lung cancer among underground miners and there is an evidence that radon is also a heath hazard in dwellings and other indoor environments. Radon accounts for about half of all human exposure to natural radiation. Radon concentration measurements were carried out in dwellings, schools and shopping centers in the Metropolitan Region of Belo Horizonte - RMBH. Most part of the inhabitants of the RMBH lives over the granitic gneissic complex, which has a variable depth out coming in some areas. For the radon concentration measurement continuous detectors, AlphaGUARD PQ2000PRO, RAD7 and Pylon Lucas Cells were used and, for Potential Alpha Energy Concentration-PAEC measurement a solid state alpha spectroscope, the DOSEman PRO was used. The experiments showed that most results are below 50 Bqm{sup -3} (mean+3{sigma}). This value is bellowing the action levels of the USEPA, ICRP and others, which varies in the range from 148 to 200 Bqm{sup -3}. The values are in the low range, as it was expected for a tropical climate. (author)

    Background This study examined the effects of 6-month nutrition education programs for community-dwelling elderly. Methods This study enrolled 50 community-dwelling elderly who regularly visit outpatient clinics. The programs had three goals: salt reduction, increase in dietary fiber, and adequate protein intake. Since it would be difficult for elderly to achieve all goals concurrently, a single goal was chosen by participants themselves. Anthropometric measurements, blood sampling, and assessment of dietary intake were performed at baseline, 3 months, and 6 months. Results The nutrition education program for salt reduction was well accepted by the participants and the amount of daily salt intake showed median value of 9.6 g at baseline, 8.0 g at 3 months and 8.1 g at 6 months (P = 0.005). The amount of dietary fiber intake only slightly increased after taking the nutrition program (median value of 13.4 g at baseline, 15.3 g at 3 months and 15.5 g at 6 months; P = 0.695), because of difficulties in introducing new food options to the diet. After taking the adequate protein intake program, participants showed small decreases in protein (a modification from 1.24 g/kg IBW to 1.20 g/kg IBW) and salt intake (8.2 to 7.3 g) at 3 months, but the effects were not sustained at 6 months. Conclusion This nutrition education program focusing on a single nutrient may serve as a strategy to successfully reduce salt intake and improve systolic blood pressure control in community-dwelling elderly individuals who regularly visit outpatient clinics. In our view, dietary and lifestyle habits should be taken into account as much as possible in nutrition education for elderly individuals. PMID:28611865

    Polypharmacy is highly prevalent among older people (65+), but little is known on the medication use of the oldest old (80+). This study explores the medication use of the Belgian community-dwelling oldest old in relation to their demographic, clinical and functional characteristics. Baseline data was used from the BELFRAIL study; a prospective, observational population-based cohort of Belgian community-dwelling patients (80+). General practitioners recorded clinical problems and medications. Medications were coded by the Anatomic Therapeutic Chemical classification. Participants' (n = 503) mean age was 84.4 years (range 80-102) and 61.2% was female. Median chronic medication use was 5 (range 0-16). Polypharmacy (≥5 medications) was high (57.7%), with excessive polypharmacy (≥10 medications) in 9.1%. Most commonly used medication group were antithrombotics, but also benzodiazepines and antidepressants were frequently consumed. Demographics related to polypharmacy (univariate analysis) were female gender, low education and moderate alcohol use. Age, care dependency and cognitive impairment showed no association with polypharmacy. In multivariate analysis, the predominant association with polypharmacy was found for multimorbidity (OR 1.78, 95% CI 1.5-2.1), followed by depression (OR 3.7, 95% CI 4.4-9.7) and physical activity (OR 0.8, 95% CI 0.7-0.9). Polypharmacy was high among Belgian community-dwelling oldest old (80+). Determinants of polypharmacy were interrelated, but dominated by multimorbidity. On top of the burden of multimorbidity, polypharmacy was independently associated with less physical activity, and with depressive symptoms.

    ​While previous versions of the International Energy Conservation Code (IECC) have included provisions to improve the air tightness of dwellings, for the first time, the 2012 IECC mandates compliance verification through blower door testing. Simply completing the Air Barrier and Insulation Installation checklist through visual inspection is no longer sufficient by itself. In addition, the 2012 IECC mandates a significantly stricter air sealing requirement. In Climate Zones 3 through 8, air leakage may not exceed 3 ACH50, which is a significant reduction from the 2009 IECC requirement of 7 ACH50. This requirement is for all residential buildings, which includes low-rise multifamily dwellings. While this air leakage rate requirement is an important component to achieving an efficient building thermal envelope, currently, the code language doesn't explicitly address differences between single family and multifamily applications. In addition, the 2012 IECC does not provide an option to sample dwellings for larger multifamily buildings, so compliance would have to be verified on every unit. With compliance with the 2012 IECC air leakage requirements on the horizon, several of CARB's multifamily builder partners are evaluating how best to comply with this requirement. Builders are not sure whether it is more practical or beneficial to simply pay for guarded testing or to revise their air sealing strategies to improve compartmentalization to comply with code requirements based on unguarded blower door testing. This report summarizes CARB's research that was conducted to assess the feasibility of meeting the 2012 IECC air leakage requirements in 3 multifamily buildings.

    Full Text Available One aspect of carbon nanotube (CNT synthesis that remains an obstacle to realize industrial mass production is the growth efficiency. Many approaches have been reported to improve the efficiency, either by lengthening the catalyst lifetime or by increasing the growth rate. We investigated the applicability of dwell time and carbon flux control to optimize yield, growth rate, and catalyst lifetime of water-assisted chemical vapor deposition of single-walled carbon nanotube (SWCNT forests using acetylene as a carbon feedstock. Our results show that although acetylene is a precursor to CNT synthesis and possesses a high reactivity, the SWCNT forest growth efficiency is highly sensitive to dwell time and carbon flux similar to ethylene. Through a systematic study spanning a wide range of dwell time and carbon flux levels, the relationship of the height, growth rate, and catalyst lifetime is found. Further, for the optimum conditions for 10 min growth, SWCNT forests with ~2500 μm height, ~350 μm/min initial growth rates and extended lifetimes could be achieved by increasing the dwell time to ~5 s, demonstrating the generality of dwell time control to highly reactive gases.

    The quantity and particle size characteristics of lead in dust released during three different paint removal techniques was determined under controlled conditions and in situ in a dwelling. Air-lead and deposited dust-lead levels were highest after sanding but 'burning-off' and 'hot-air' removal methods also produced significant contamination. The importance of dust particle-size and lead is discussed in relation to the potential hazard to home renovators via inhalation and to children via the 'hand-to-mouth' route.

    Refugees often experience compromised health from both pre- and post-migration stressors. Coalition theory has helped guide the development of targeted programs to address the health care needs of vulnerable populations. Using the Community Coalition Action Theory as a framework, a coalition was formed to implement a community garden with apartment-dwelling refugees. Outcomes included successful coalition formation, a community garden, reported satisfaction from all gardeners with increased vegetable intake, access to culturally meaningful foods, and evidence of increased community engagement. The opportunity for community health nurses to convene a coalition to affect positive health for refugees is demonstrated.

    Mismanaged anger is associated with adverse health outcomes. This study examined whether dimensions of religiousness/spirituality could predict healthy anger management in a sample of 82 community-dwelling older Americans. A correlational research design was employed using the Deffenbacher Anger Scale and the Brief Multidimensional Measure of Religiousness/Spirituality. Higher scores on Forgiveness, Daily Spiritual Experiences, Religiousness/Spirituality as Coping, and Self-Ranking of Religiousness/Spirituality were correlated with healthier anger management; however forgiveness was the only significant predictor in the regression analysis. Interventions to facilitate forgiveness may promote healthy anger management and minimize the adverse health effects of mismanaged anger.

    2013-01-01

    Full Text Available This study is a retrospective chart review comparing rural-dwelling Caucasian and Hispanic outpatients’ attribution of depressive symptoms. Based on the data gathered at intake, Hispanics were more likely to attribute depression to curse/spell and supernatural causes, while Caucasians were more likely to attribute symptoms to hereditary factors or job stress. Among both groups, higher CESD score was associated with problems with significant others or how they got along with others. Among Hispanics, depression severity was additionally associated with problems related to job or finances. Our findings point to a consequential role for clinical inquiry into attributed causes of depressive symptoms.

    Studies have shown that source dwells within Varian's HDR CT/MR compatible ring applicators can deviate from intended positions by several millimeters. Quantifying this offset is an important part of commissioning. The aims of this study were to: 1) determine the reproducibility of the offset, 2) study the interobserver variation in the offset's measurement, and 3) quantify the dosimetric impact of the offset. Offsets were measured for four ring applicators: two 30°, one 45°, and one 60°. Dwell positions were measured five times for each ring to determine the reproducibility of source positioning. Experiments were done to compare two separate source wires, as well as different time points within a single source wire's lifecycle. Data were analyzed by three independent observers. To quantify the dosimetric impact of the offset, a treatment plan was generated using BrachyVision. The dose to point A, and the D(2cc) metric for rectum and bladder were calculated with and without the offset. For the 45° and 60° rings, measured offsets were 3.0 mm and 3.6 mm, respectively. The 30° ring showed substantial variation in distal dwell positions (maximum difference between the five experiments of 2.9 mm). Subsequent testing of a replacement ring showed an offset of 2.4 mm that was more reproducible. Offsets varied less than 1 mm between different source wires, and changed less than 1 mm over the course of a source wire's lifecycle. When comparing observers, the average range in a measurement of a dwell position was 0. 5 mm (σ = 0.2 mm, max 1.3 mm). The offset resulted in dose variations to point A, bladder, and rectum of less than 1%, 2%, and 5%, respectively. Results indicate that Varian rings can show systematic and random offsets of more than 3 mm. Some can be considered defective and should be replaced. Each applicator should be individually commissioned and reproducibility should be confirmed with multiple tests.

    This paper deals with the model reduction problem of continuous-time switched linear systems with finite-frequency input signals. The objective of the paper is to propose a finite-frequency model reduction method for such systems. A finite-frequency ? performance index is first defined in frequency domain, and then a finite-frequency performance analysis condition is derived by Parseval's theorem. Combined with the average dwell time approach, sufficient conditions for the existence of exponentially stable reduced-order models are derived. An algorithm is proposed to construct the desired reduced-order models. The effectiveness of the proposed method is illustrated by a numerical example.

    The International Space Station (ISS) currently provides human waste collection and hygiene facilities in the Russian Segment Service Module (SM) which supports a three person crew. Additional hardware is planned for the United States Operational Segment (USOS) to support expansion of the crew to six person capability. The additional hardware will be integrated in an ISS standard equipment rack structure that was planned to be installed in the Node 3 element; however, the ISS Program Office recently directed implementation of the rack, or Waste and Hygiene Compartment (WHC), into the U.S. Laboratory element to provide early operational capability. In this configuration, preserved urine from the WHC waste collection system can be processed by the Urine Processor Assembly (UPA) in either the U.S. Lab or Node 3 to recover water for crew consumption or oxygen production. The human waste collection hardware is derived from the Service Module system and is provided by RSC-Energia. This paper describes the concepts, design, and integration of the WHC waste collection hardware into the USOS including integration with U.S. Lab and Node 3 systems.

    Which clinical measures of walking performance best predict free-living physical activity in community-dwelling people with stroke? Cross-sectional observational study. 42 community-dwelling stroke survivors. Predictors were four clinical measures of walking performance (speed, automaticity, capacity, and stairs ability). The outcome of interest was free-living physical activity, measured as frequency (activity counts) and duration (time on feet), collected using an activity monitor called the Intelligent Device for Energy Expenditure and Physical Activity. Time on feet was predicted by stairs ability alone (B 166, 95% CI 55 to 278) which accounted for 48% of the variance. Activity counts were also predicted by stairs ability alone (B 6486, 95% CI 2922 to 10 050) which accounted for 58% of the variance. The best predictor of free-living physical activity in community-dwelling people with stroke was stairs ability.

    [Purpose] The purpose of this study was to investigate the psychometric properties of the lower extremity subscale of the Fugl-Meyer Assessment lower extremity (FMA-LE) for community-dwelling hemiplegic stroke patients. [Subjects] The participants were 140 community-dwelling hemiplegic stroke patients. [Methods] To determine the psychometric properties of the FMA-LE, we examined construct validity, response characteristics, item discrimination, and internal consistency. [Results] Factor analysis of the FMA-LE revealed that the first factor explained 61.73% of the variance and provided evidence of unidimensionality. The FMA-LE did not show ceiling or floor effects; Cronbach's α was 0.935 (95% CI: 0.919-0.950). [Conclusion] Because the FMA-LE seems to be both valid and reliable, we conclude that it is appropriate for the measurement of the lower extremity motor impairment of community-dwelling hemiplegic stroke patients.

  15. Fission yeast mtr1p regulates interphase microtubule cortical dwell-time

    2014-06-01

    Full Text Available The microtubule cytoskeleton plays important roles in cell polarity, motility and division. Microtubules inherently undergo dynamic instability, stochastically switching between phases of growth and shrinkage. In cells, some microtubule-associated proteins (MAPs and molecular motors can further modulate microtubule dynamics. We present here the fission yeast mtr1+, a new regulator of microtubule dynamics that appears to be not a MAP or a motor. mtr1-deletion (mtr1Δ primarily results in longer microtubule dwell-time at the cell tip cortex, suggesting that mtr1p acts directly or indirectly as a destabilizer of microtubules. mtr1p is antagonistic to mal3p, the ortholog of mammalian EB1, which stabilizes microtubules. mal3Δ results in short microtubules, but can be partially rescued by mtr1Δ, as the double mutant mal3Δ mtr1Δ exhibits longer microtubules than mal3Δ single mutant. By sequence homology, mtr1p is predicted to be a component of the ribosomal quality control complex. Intriguingly, deletion of a predicted ribosomal gene, rps1801, also resulted in longer microtubule dwell-time similar to mtr1Δ. The double-mutant mal3Δ rps1801Δ also exhibits longer microtubules than mal3Δ single mutant alone. Our study suggests a possible involvement of mtr1p and the ribosome complex in modulating microtubule dynamics.

    Evidence of extinction debts for the global distributions of forest-dwelling reptiles, mammals and amphibians was tested and the debt magnitude was estimated and mapped. By using different correlation tests and variable importance analysis, the results showed that spatial richness patterns for the three forest-dwelling terrestrial vertebrate groups had significant and stronger correlations with past forest cover area and other variables in the 1500 s, implying the evidence for extinction debts. Moreover, it was likely that the extinction debts have been partially paid, given that their global richness patterns were also significantly correlated with contemporary forest variables in the 2000 s (but the absolute magnitudes of the correlation coefficients were usually smaller than those calculated for historical forest variables). By utilizing species-area relationships, spatial extinction-debt magnitudes for the three vertebrate groups at the global scale were estimated and the hotspots of extinction debts were identified. These high-debt hotspots were generally situated in areas that did not spatially overlap with hotspots of species richness or high extinction-risk areas based on IUCN threatened status to a large extent. This spatial mismatch pattern suggested that necessary conservation efforts should be directed toward high-debt areas that are still overlooked.

    Given the increasing elderly population worldwide, the identification of potential determinants of successful ageing is important. Many studies have shown that parenting style and mental resilience may influence mental health; however, little is known about the psychological mechanisms that underpin this relationship. The current study sought to explore the relationships among mental resilience, perceptions of parents' parenting style, and depression and anxiety among community-dwelling elderly adults in China. In total, 439 community-dwelling elderly Chinese adults aged 60-91 years completed the Personal and Parents' Parenting Style Scale, Connor-Davidson Resilience Scale, Zung Self-Rating Depression Scale, and Zung Self-Rating Anxiety Scale. Elderly adults whose parents preferred positive and authoritative parenting styles had higher levels of mental resilience and lower levels of depression and anxiety. Elderly adults parented in the authoritarian style were found to have higher levels of depression and anxiety, with lower mental resilience. The findings of this study provide evidence related to successful ageing and coping with life pressures, and highlight the important effects of parenting on mental health. The results suggest that examination of the proximal determinants of successful ageing is not sufficient-distal factors may also contribute to the 'success' of ageing by modifying key psychological dispositions that promote adaptation to adversity.

This study aimed to investigate the effect of structured interventions comprising music, physical exercise, and reminiscence therapy on cognitive function and quality of life of the community-dwelling elderly. [Subjects and Methods] The study included 15 community-dwelling elderly people who used a day-care center. Participants underwent sessions comprising the following three factors: 1) singing songs familiar to the elderly; 2) physical exercise to music; and 3) observation of historical pictures. Sessions were conducted once or twice per week, 30 to 40 min per day, for 10 weeks. Pre and post interventions of the Mini Mental State Examination, the Behavioral Rating Scale for the Elderly, and the SF-8 were compared. [Results] No significant difference was observed between pre- and post-intervention scores on the Mini Mental State Examination and the Behavioral Rating Scale for the Elderly. However, the post intervention physical component summary of SF-8 was significantly higher than the pre intervention summary. [Conclusion] This study suggests that interventions comprising music, physical exercise, and reminiscence therapy may contribute toward the improvement of elderly individuals' health-related quality of life, especially physical health.

    Full Text Available Abstract Background Studies of the associations between diet and depression have primarily focused on single nutrients or foods. Recently, dietary patterns representing a combination of foods have attracted more interest than individual nutrient. The objective of this study was to examine the association between dietary patterns and depressive symptoms among a community-dwelling population in Japan. Methods We examined the association between dietary patterns and the risk of depression among 791 Japanese community-dwelling individuals. Diet was assessed with a validated brief-type self-administered diet history questionnaire (BDHQ. Dietary patterns from 52 predefined food groups [energy-adjusted food (g/d] were extracted by principal component analysis. The Center for Epidemiologic Studies Depression Scale (CES-D with a cut-off point of 16 was used to assess the prevalence of depression. Results A total of 97 subjects (12.3% were classified as having depression. Four dietary patterns were identified: “Healthy”, “Western”, “Bread and confectionery”, and “Alcohol and accompanying” dietary patterns. After adjusting for potential confounders, the dietary patterns were not related to the risk of depression. Conclusions The present study failed to find associations between dietary patterns and the risk of depression. However, the interpretation of our results was hampered by the lack of certain data, including employment physical activity and longitudinal observations. Potential associations between dietary patterns and depressive symptoms were not completely ruled out. Future research exploring dietary patterns and depressive symptoms is warranted.

    Full Text Available Background: This study was aimed to assess agreement and diagnostic accuracy of the Iranian version of Mini Nutritional Assessment short-form (MNA-SF against the original MNA, as a gold standard in community-dwelling elderly. Methods: The full MNA and 9-item MNA-SF comprising questions regarding clinical status, dietary assessment and self-perception of health status and nutri-tion together with mid-arm and calf circumference measurements without in-cluding the body mass index (BMI were completed for 205 volunteers aged 65 or older recruited from all over Markazi Province (Iran. Correlation, diagnostic accuracy and agreement between the MNA-SF and full MNA were calculated. Results: The MNA and the MNA-SF classified 45.4% and 64.4% of the sub-jects as malnourished or at risk of malnutrition, respectively. Substantial agree-ment between the MNA-SF and full MNA was observed (Kappa=0.633. The MNA-SF correlated strongly with the full MNA (r=0.868, P<0.001. The MNA-SF showed high sensitivity (96.77% and negative predictive values (95.89%, relatively high specificity (62.5% and positive predictive values (68.18% and fair accuracy (Area under curve =0.796. Conclusion: Iranian MNA-SF seems to be an applicable screening tool for quick detection of malnutrition or at risk of malnutrition in community-dwelling elderly especially when BMI is unavailable.

  3. Benzodiazepines for insomnia in community-dwelling elderly: a review of benefit and risk.

    1995-11-01

    To critically assess and summarize the beneficial effects of benzodiazepine therapy for insomnia in community-dwelling elders, a systematic search was undertaken to review all published clinical trials and sleep laboratory studies. The risk of injury for benzodiazepine users was also reviewed. Ten studies met inclusion criteria for assessing benefit. There are no studies regarding the long-term effectiveness of benzodiazepines for the treatment of sleep disorders in the elderly. In the sleep laboratory setting, triazolam 0.125 mg, flurazepam 15 mg, and estazolam 1 mg improved sleep latency by 27 to 30 minutes and increased total sleep time by 47 to 81 minutes for the first 2 to 3 nights of treatment, compared with baseline measurements taken while the patients were receiving placebo. In contrast to these modest short-term benefits, there is an association between the use of benzodiazepines with a long half-life, eg, flurazepam, diazepam, and chlordiazepoxide, and an increased risk of hip fracture in the elderly. Triazolam can cause rebound insomnia as well as anterograde amnesia. Clinicians should discontinue their prescribing of long-acting benzodiazepines for elderly patients with insomnia. More research is needed on the effects of nondrug interventions as well as on short- and intermediate-acting benzodiazepines, such as oxazepam and temazepam, to treat insomnia in community-dwelling elderly.

    This study investigated participation in leisure activities in urban-dwelling elderly persons in Korea and its role in predicting quality of life. The participated activities over a 48-hour period were recorded by each participant, and amount of participated time for each activity was calculated. Correlational analysis examined the relationship between the degree of participation in domains of leisure activity and quality of life. Multiple regression analysis was conducted to determine which leisure activity participation predicted quality of life. The results indicated that the participants spent the most time in "use of media". Quality of life showed a positive correlation with "use of media", "sports and outdoor leisure activity" and "hobby and other leisure activity". The results of hierarchical multiple regression analysis found that use of media, "religious activity", sports and outdoor leisure activity and hobby and other leisure activity significantly predicted quality of life after controlling for the effects of demographic variables. Of these variables, hobby and other leisure activity was the strongest predictor of quality of life. The results will augment treatment planning and activity management in enhancing quality of life by allied health professionals, especially occupational therapists. The findings are limited in that the sample consisted of urban-dwelling elderly primarily with a religious affiliation. It is recommended that a cross-cultural investigation using standard assessment measures be conducted to validate whether there is indeed similarities in time use and leisure activity participation in the elderly in different cultures.

    Life Cycle Assessment (LCA) has been applied within the residential building sector of two buildings, one in each a developed (Spain) and a developing (Colombia) country. The main goal of this paper involves the environmental loads and also brings together the operational energy for activities during the operation phase such as HVAC, domestic hot water, electrical appliances, cooking and illumination. The present research compares two real scenarios: Situation 1, where 100% of the dwelling's energy is supplied with electricity only and Situation 2, where dwellings can be operated with natural gas plus electricity. The results for the environmental impacts using natural gas plus electricity show that of the Spanish environmental impacts air conditioning had the highest impact with approximately 27-42% due to the electricity used to power it. In Colombian results showed that electrical appliances had the highest environmental impacts in the same order of magnitude with approximately 60% and cooking had the best reduction of emissions due to the use of natural gas, from 10% down to less than 2%. The origin of the energy source used in each Country plays an important role to minimize environmental impacts, as was demonstrated by the environmental impacts of its use in Colombia where 78% of the electricity came from hydroelectric plants whereas in Spain it is more mixed, fossil fuels represented 55%, nuclear 18% and wind 9%. In summary, LCA has been applied because this methodology supports the decision making to concern environmental sustainability. (author)

    Full Text Available Coral-associated invertebrates form a major part of the diversity on reefs, but their distribution and occurrence patterns are virtually unstudied. For associated taxa data are lacking on their distribution across shelves and environmental gradients, but also over various depths. Off Curaçao we studied the prevalence and density of coral-dwelling gall crabs (Cryptochiridae, obligate symbionts of stony corals. Belt transects (10 × 0.5m2 were laid out at 6, 12 and 18 m depth intervals at 27 localities. Twenty-one known host coral species were surveyed, measured, and the number of crab dwellings was recorded to study the influence of host occurrence, depth distribution, and colony size on the occurrence rates of three Atlantic gall crab species: Opecarcinus hypostegus, Troglocarcinus corallicola and Kroppcarcinus siderastreicola. The overall gall crab prevalence rate was 20.3% across all available host corals at all depths. The agariciid-associated species O. hypostegus was found to mostly inhabit Agaricia lamarcki and its prevalence was highest at deeper depths, following the depth distribution of its host. Kroppcarcinus siderastreicola, associated with Siderastrea and Stephanocoenia, inhabited shallower depths despite higher host availability at deeper depths. The generalist species T. corallicola showed no clear host or depth specialisation. These results show that the primary factors affecting the distribution and occurrence rates over depth intervals differed between each of the three Atlantic cryptochirid species, which in turn influences their vulnerability to reef degradation.

    Full Text Available Dehydration is common among elderly people. The aim of this study was to perform validation analysis of a geriatric dehydration-screening tool (DST in the assessment of hydration status in elderly people. This tool was based on the DST proposed by Vivanti et al., which is composed by 11 items (four physical signs of dehydration and seven questions about thirst sensation, pain and mobility, with four questions extra about drinking habits. The resulting questionnaire was evaluated in a convenience sample comprising institutionalized (n = 29 and community-dwelling (n = 74 elderly people. Urinary parameters were assessed (24-h urine osmolality and volume and free water reserve (FWR was calculated. Exploratory factor analysis was used to evaluate the scale’s dimensionality and Cronbach’s alpha was used to measure the reliability of each subscale. Construct’s validity was tested using linear regression to estimate the association between scores in each dimension and urinary parameters. Two factors emerged from factor analysis, which were named “Hydration Score” and “Pain Score”, and both subscales showed acceptable reliabilities. The “Hydration Score” was negatively associated with 24-h urine osmolality in community-dwelling; and the “Pain Score” was negatively associated with 24-h urine osmolality, and positively associated with 24-h urine volume and FWR in institutionalized elderly people.

    The purposes of this paper are to explore, from a theoretical perspective, explanations for why some community-dwelling elders self-impose activity limitations (SIALs); to develop an integrated explanation for SIAL from a nursing perspective; and to identify some clinical implications of relevance to public health nursing practice. Activity limitation is an important risk factor for functional decline, morbidity, and mortality among community-dwelling elders. Many studies have focused on disease and environmental influences on activity limitations. The intrinsic processes associated with voluntary or SIAL in old age among otherwise physically and mentally capable elders are poorly understood and little studied. The conceptualization of SIAL provides nurses with an understanding of an understudied aging phenomenon and helps nurses understand how elders see activities related to their life priorities. The conceptual framework will facilitate future qualitative and quantitative study of SIAL, assist nurses in the development of a new gerontological nursing theory, and design of interventions for elders with activity limitations. Public health nurses with a better understanding of SIAL may be able to help elders improve or maintain their independence.

    Evidence of extinction debts for the global distributions of forest-dwelling reptiles, mammals and amphibians was tested and the debt magnitude was estimated and mapped. By using different correlation tests and variable importance analysis, the results showed that spatial richness patterns for the three forest-dwelling terrestrial vertebrate groups had significant and stronger correlations with past forest cover area and other variables in the 1500 s, implying the evidence for extinction debts. Moreover, it was likely that the extinction debts have been partially paid, given that their global richness patterns were also significantly correlated with contemporary forest variables in the 2000 s (but the absolute magnitudes of the correlation coefficients were usually smaller than those calculated for historical forest variables). By utilizing species-area relationships, spatial extinction-debt magnitudes for the three vertebrate groups at the global scale were estimated and the hotspots of extinction debts were identified. These high-debt hotspots were generally situated in areas that did not spatially overlap with hotspots of species richness or high extinction-risk areas based on IUCN threatened status to a large extent. This spatial mismatch pattern suggested that necessary conservation efforts should be directed toward high-debt areas that are still overlooked. PMID:28300200

    Recreational disturbance associated with trails has been identified as one of the major factors causing a decline of native biodiversity within protected areas. However, despite the negative impacts that recreation can have on biodiversity, providing public access to nature is critical for the future of the conservation of biodiversity. As such, many protected area managers are looking for tools to help maintain a balance between public access and biodiversity conservation. The objectives of this study were to examine the impacts of recreational trails on forest-dwelling bird communities in eastern North America, identify functional guilds which are particularly sensitive to recreational trails, and derive guidelines for trail design to assist in managing the impacts of recreational trails on forest-dwelling birds. Trails within 24 publicly owned natural areas were mapped, and breeding bird communities were described with the use of point count surveys. The density of forest birds, particularly of those species which nest or forage on the ground, were significantly positively influenced by the amount of trail-free refuge habitat. Although management options to control trail use in non-staffed protected areas are limited, this study suggests that protected area managers could design and maintain a trail network that would minimize impacts on resident wildlife, while providing recreational opportunities for visitors, by designing their trail network to maximize the area of trail-free habitat.

    To empower older consumers and improve health outcomes, a consumer-friendly personal health record (PHR) is needed. The purpose of this article was to evaluate PHR technology and content for older community-dwelling consumers. Specific aims were to: (a) develop a secure, web-based application for a PHR to enable interoperable exchanges of data between consumers and clinicians; (b) develop structured, evidence-based shared care plan content for the PHR using an interface terminology standard; and (c) validate the shared care plans with consumers. An interoperable web-based form was developed. The standardized PHR content was developed by expert panel consensus using the Omaha System problem list and care plans, and validated by consumer interviews. Evidence-based shared care plans for 21 problems common among community-dwelling older adults were developed and encoded with Omaha System terms for data capture in the PHR. An additional problem, Neighborhood-workplace safety, was identified by consumers and will be added to the care plans.

    Elder self-neglect is an important public health issue. However, little is known about the association between personality traits and risk of elder self-neglect among community-dwelling populations. The objectives of this study are as follows: 1) to examine the association of personality traits with elder self-neglect and 2) to examine the association of personality traits with elder self-neglect severity. Population-based study conducted from 1993 to 2005 of community-dwelling older adults (N = 9,056) participating in the Chicago Health Aging Project (CHAP). Subsets of the CHAP participants (N = 1,820) were identified for suspected self-neglect by social services agency, which assessed the severity. Personality traits assessed included neuroticism, extraversion, rigidity, and information processing. Logistic and linear regressions were used to assess these associations. In the bivariate analyses, personality traits (neuroticism, extraversion, information processing, and rigidity) were significantly associated with increased risk of elder self-neglect. However, after adjusting for potential confounders, the above associations were no longer statistically significant. In addition, personality traits were not associated with increased risk of greater self-neglect severity. Furthermore, interaction term analyses of personality traits with health and psychosocial factors were not statistically significant with elder self-neglect outcomes. Neuroticism, extraversion, rigidity, and information processing were not associated with significantly increased risk of elder self-neglect after consideration of potential confounders.

    Little correlations has been found between contemporary radon gas measurements made in the past and retrospective radon gas measurements in Irish dwellings. This would suggest that these two techniques would result in two significantly different cumulative radon exposure estimates. Contemporary radon gas measurements made a few years apart in the same room of a dwelling were found to be significantly different. None of these differences could be explained by known changes to the rooms themselves., such ventilation or structural alterations to the room. This highlights the limitations of the contemporary radon gas measurements as a surrogate measurement for use in residential radon epidemiology. The contemporary radon gas measurements made by the Radiological Protection Institute of Ireland (R.P.I.I.) and University College of Dublin (U.C.D.) do not cover the same exposure period as the retrospective estimates and so the accuracy of the retrospective measurements cannot be demonstrated. A weak correlation can be seen between the retrospective radon gas estimates and a combination of the two contemporary radon gas estimates. It is not unreasonable to expect improvement in the correlation if further contemporary radon gas measurements were made in these rooms. (N.C.)

    Characteristics of radon and its progeny were investigated in different air conditions by turning four types of indoor air appliances on and off in a two-story concrete Japanese dwelling. The four appliances were air conditioner, air cleaner, gas heater and cooker hood. The measurements were done using two devices: (1) a Si-based semiconductor detector for continuous measurement of indoor radon concentration and (2) a ZnS(Ag) scintillation counting system for equilibrium-equivalent radon concentration. Throughout the entire experiment, the cooker hood was the most effective in decreasing indoor radon concentration over a long period of time and the less effective was the air conditioner, while the air cleaner and gas heater did not affect the concentration of radon. However, the results measured in each air condition will differ according to the lifestyles and activities of the inhabitants. In this study, indoor radon and its progeny in a Japanese dwelling will be characterised by the different air conditions.

    Global warming threatens to reduce population connectivity for terrestrial wildlife through significant and rapid changes to sea ice. Using genetic fingerprinting, we contrasted extant connectivity in island-dwelling Peary caribou in northern Canada with continental-migratory caribou. We next examined if sea-ice contractions in the last decades modulated population connectivity and explored the possible impact of future climate change on long-term connectivity among island caribou. We found a strong correlation between genetic and geodesic distances for both continental and Peary caribou, even after accounting for the possible effect of sea surface. Sea ice has thus been an effective corridor for Peary caribou, promoting inter-island connectivity and population mixing. Using a time series of remote sensing sea-ice data, we show that landscape resistance in the Canadian Arctic Archipelago has increased by approximately 15% since 1979 and may further increase by 20-77% by 2086 under a high-emission scenario (RCP8.5). Under the persistent increase in greenhouse gas concentrations, reduced connectivity may isolate island-dwelling caribou with potentially significant consequences for population viability.

    Falls are a leading cause of fatal and nonfatal injuries among the elderly. Accurate determination of risk factors associated with falls in older adults is necessary, not only for individual patient management, but also for the development of fall prevention programs. The purpose of this study was to evaluate the effectiveness of clinical measures, such as the one-legged stance test (OLST), sit-to-stand test (STST), manual muscle tests (MMT), and response speed in predicting faller status in community-dwelling older adults (N = 94, age 60-89 years). The variables assessed were single-leg standing (as measured by OLST), STST, and MMT of 12 different muscle groups (hip flexors, hip abductors, hip adductors, knee flexors, knee extensors, ankle dorsiflexors, ankle plantarflexors, shoulder flexors, shoulder abductors, elbow flexors, elbow extensors, and finger flexors), and speed of response (as measured by a visual hand reaction and movement time task). Of the 94 older adults assessed, 28 (29.7%) reported at least one fall within the previous year. The discriminant analysis revealed that there were six variables that significantly discriminated between fallers and nonfallers. These variables included MMT of the ankle dorsiflexors, knee flexors, hip abductors, and knee extensors, as well as time on the OLST and the STST. The results indicate that simple clinical measures of musculoskeletal function can discriminate fallers from nonfallers in community-dwelling older adults.

    Cognitive deficits have been reported in older cardiac patients. An underlying mechanism for these findings may be reduced cardiac function. The relationship between cardiac function as represented by different echocardiographic measures and different cognitive function domains in older cardiac patients remains unknown. An older (≥70 years) heterogeneous group of 117 community-dwelling cardiac patients under medical supervision by a cardiologist underwent thorough echocardiographic assessment including left ventricular ejection fraction, cardiac index, left atrial volume index, left ventricular mass index, left ventricular diastolic function, and valvular calcification. During a home visit, a neuropsychological assessment was performed within 7.1 ± 3.8 months after echocardiographic assessment; the neuropsychological assessment included three subtests of a word-learning test (encoding, recall, recognition) to examine one memory function domain and three executive function tests, including digit span backwards, Trail Making Test B minus A, and the Stroop colour-word test. Regression analyses showed no significant linear or quadratic associations between any of the echocardiographic functions and the cognitive function measures. None of the echocardiographic measures as representative of cardiac function was correlated with memory or executive function in this group of community-dwelling older cardiac patients. These findings contrast with those of previous studies. © 2017 Japanese Psychogeriatric Society.

    Stroke is not gender-discriminatory. Yet, the subject of stroke among females has apparently not received significant attention from clinical researchers. The consequences of stroke include functional and psychosocial sequelae which may cause disability, hinder community reintegration and restrict participation. The inter-relationships among functional ability, community reintegration and participation restriction of community-dwelling, female stroke survivors in Ibadan were assessed in this descriptive study. Fifty-two community-dwelling female stroke survivors (mean age = 56.55±9.91 years) were surveyed using consecutive sampling technique. Their functional ability level was measured using the Functional Independence Measure (FIM) while London Handicap Scale (LHS) was used to assess their participation restriction. Data were analyzed using Spearman Rank Correlation Coefficient (rho) and Mann-Whitney U test at p = 0.05. Significantly positive correlations (preintegration (r = 0.54; p = 0.01) as well as between participation restriction and community reintegration (r = 0.34; p = 0.05). Individuals with left hemiplegia had significantly higher mean rank scores in functional ability (30.41) than those who had right hemiplegia (mean rank scores = 21.94). Functional ability which appears to be related to stroke laterality showed positive association with both community reintegration and participation restriction. This suggests that improving the functional ability of the stroke survivors may reduce participation restriction and enhance their reintegration into the community. A similar study which compares male and female stroke survivors in the same community is thus necessary.

    To determine whether the presence of depressive symptoms is an independent risk factor for disabling back pain in community-dwelling older persons. Prospective cohort study with a 12-month follow-up period. General community. Seven hundred forty-four members of a large health plan who were aged 70 and older and independent in bathing, walking, dressing, and transferring at baseline. The presence of depressive symptoms, defined as a score of 16 or greater on the Center for Epidemiologic Studies-Depression Scale, was documented during a comprehensive baseline assessment that also included information regarding participants' demographic, medical, and physical/cognitive status. The occurrence of disabling back pain was ascertained during monthly telephone interviews. Depressive symptoms were present in 153 (20.6%) participants at baseline. Over the 12-month follow-up period, 186 participants (25.0%) reported disabling back pain during 1 to 2 months and 91 (12.2%) during 3 or more months. After adjustment for potential confounders, the presence of depressive symptoms was independently associated with the occurrence of disabling back pain (adjusted odds ratio (AOR)=2.3 (95% confidence interval (CI)=1.2-4.4) for 1 to 2 months with disabling back pain; AOR=7.8 (95% CI=3.7-16.4) for 3 or more months with disabling back pain). The presence of depressive symptoms is a strong, independent, and highly prevalent risk factor for the occurrence of disabling back pain in community-dwelling older persons.

    Full Text Available One of the most acute problems of modern society are issues related to the globalization of mankind caused by the next small scientific and technological revolution that is taking place and the emerging transition to a post-industrial society. Some of their characteristic features of this society are: deterritoriality, weakening of functional-spatial ties between places of residence, the application of labor and recreation rights. The peculiarity of the emerging new architecture with the arrival of the postindustrial information society is becoming completely new approaches to the formation of cities and the human dwelling itself. The article deals with the application of additive technologies in the production of mobile residential objects of high factory readiness. The article describes the concept of the formation of a mobile dwelling cluster type based on the principles of the organization of intelligent self-adapting systems (Smart Development, gives examples of author’s developments in the field of cluster housing, with a description of the fundamental principles necessary for the possibility of further development and technical implementation.

    Full Text Available Sustainability of cities and the environmental implications of high resource utilization by the domestic sector are growing concerns related to urban regions. Well-informed urban planning decision-making is an essential tool to help in the task and, for that, an important point to consider is the influence of parameters like residential density and housing typology on the intensity of resource utilization. Emergy synthesis, a life-cycle energy analysis methodological approach that considers the interaction of natural and human-made flows, was used to evaluate the environmental support for dwelling operational stage in five typical present-day housing units on the island of Montreal. As expected, resource utilization, measured as total emergy used, was positively correlated to housing unit size both with respect to number of occupants and dwelling size. Results suggest that variables affecting notably the intensity of resource utilization are per household income and per dweller habitable space and, while a higher income increased per capita emergy in all cases, increasing space availability per resident did not result in a decrease of empower density after 50 m2/person. Future work should consider lower and higher densities and analyses at the scale of blocks, neighborhoods and urban planning zones.

    Full Text Available To understand the global distribution patterns of litter-dwelling thrips, a total 150 leaf litter samples were collected from 6 natural reserves located in three climatic regions, temperate, subtropical and tropical. The results showed the relative abundance of Thysanoptera was over 3.0% in 4 natural reserves from subtropical and tropical zone, and reached 5.9% in one tropical reserve, only less than Acarina and Collembola. In contrast it was only 0.3% in the warm temperate natural reserves, and no thrips were collected in a mid temperate reserve. The order on the average species numbers per plot of litter thrips was tropic > subtropics > temperate (n=25, p<0.05. Mean density of litter thrips per plots in the tropics and subtropics was significantly higher than that in the temperate region (n=25, p<0.05, but the average density was not significantly different between tropical and subtropical zones (n=25, p>0.05. The diversity of litter thrips in the tropics and subtropics was much higher than that in the temperate area based on comparsions of Shannon-Wiener diversity index (H΄, Pielou eveness index (J, and Simpson dominance index (D. All of these results indicated that litter-dwelling thrips lived mainly in tropical and subtropical regions; meanwhile, species number and relative abundance increased with decreasing latitude.

  4. Distribution of dwell times of a ribosome: effects of infidelity, kinetic proofreading and ribosome crowding

    Ribosome is a molecular machine that polymerizes a protein where the sequence of the amino acid subunits of the protein is dictated by the sequence of codons (triplets of nucleotide subunits) on a messenger RNA (mRNA) that serves as the template. The ribosome is a molecular motor that utilizes the template mRNA strand also as the track. Thus, in each step the ribosome moves forward by one codon and, simultaneously, elongates the protein by one amino acid. We present a theoretical model that captures most of the main steps in the mechano-chemical cycle of a ribosome. The stochastic movement of the ribosome consists of an alternating sequence of pause and translocation; the sum of the durations of a pause and the following translocation is defined as the time of dwell of the ribosome at the corresponding codon. We present an analytical calculation of the distribution of the dwell times of a ribosome in our model. Our theoretical prediction is consistent with the experimental results reported in the literature.

    Ribosome is a molecular machine that polymerizes a protein where the sequence of the amino acid residues, the monomers of the protein, is dictated by the sequence of codons (triplets of nucleotides) on a messenger RNA (mRNA) that serves as the template. The ribosome is a molecular motor that utilizes the template mRNA strand also as the track. Thus, in each step the ribosome moves forward by one codon and, simultaneously, elongates the protein by one amino acid.

The stochastic movement of the ribosome consists of an alternating sequence of pause and translocation; the sum of the durations of a pause and the following translocation is the time of dwell of the ribosome at the corresponding codon. We derive the analytical expression for the distribution of the dwell times of a ribosome in our model. Wherever experimental data are available, our theoretical predictions are consistent with those results. We suggest appropriate experiments to test the new predictions of our model, particularly the effects of the quality control mechanism of the ribosome and that of their crowding on the mRNA track.

    Full Text Available Objective: To assess potentially inappropriate prescribing (PIP using Beers (2012 version and STOPP (2008 version criteria in polypharmacy, community-dwelling, older patients. Methods: From the information collected in the invoicing data of the prescriptions and the electronic medical records, a sample was selected of 223 ≥ 65-year-old patients who were taking simultaneously 10 or more drugs per day. Beers and STOPP criteria were separately applied, and the results obtained with the two methods were compared. Results: A total of 141 (63.2% patients presented at least one Beers criterion. The two most frequently observed Beers criteria independent of diagnosis were the use of benzodiazepines and the use of non-COX-2-selective non-steroidal anti-inflammatory drugs. With regard to Beers criteria considering diagnosis, the most frequent were the use of anticholinergic drugs in patients with lower urinary tract symptoms or benign prostatic hyperplasia, and the use of benzodiazepines, antipsychotics, zolpidem or H2-antihistamines, in patients with dementia or cognitive impairment. A total of 165 (73.9% patients had at least one PIP according to the STOPP criteria. Duplicate drug classes and long-term use of long-acting benzodiazepines were the two most frequent STOPP criteria. Discussion: Our study identified a high frequency of PIP in polymedicated community-dwelling older patients. Simultaneous application of Beers and STOPP criteria represents a useful tool to improve prescribing in this population group.

    To summarize evidence regarding the health outcomes associated with polypharmacy, defined as number of prescribed medications, in older community-dwelling persons. Systematic review of MEDLINE (OvidSP 1946 to May, Week 3, 2014). Community. Observational studies examining health outcomes according to number of prescription medications taken. Association between number of medications and health outcomes. Because of the importance of comorbidity as a potential confounder of the relationship between polypharmacy and health outcomes, articles were assessed regarding the quality of their adjustment for confounding. Of the 50 studies identified, the majority that were rated good in terms of their adjustment for comorbidity demonstrated relationships between polypharmacy and a range of outcomes, including falls, fall outcomes, fall risk factors, adverse drug events, hospitalization, mortality, and measures of function and cognition. However, a number of these studies failed to demonstrate associations, as did a substantial proportion of studies rated fair or poor. Data are mixed regarding the relationship between polypharmacy, considered in terms of number of medications, and adverse outcomes in community-dwelling older persons. Because of the challenge of confounding, randomized controlled trials of medication discontinuation may provide more-definitive evidence regarding this relationship than observational studies can provide. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

  8. Residents’ Experiences of Privacy and Comfort in Multi-Storey Apartment Dwellings in Subtropical Brisbane

    Full Text Available Dwellings in multi-storey apartment buildings (MSAB are predicted to increase dramatically as a proportion of housing stock in subtropical cities over coming decades. The problem of designing comfortable and healthy high-density residential environments and minimising energy consumption must be addressed urgently in subtropical cities globally. This paper explores private residents’ experiences of privacy and comfort and their perceptions of how well their apartment dwelling modulated the external environment in subtropical conditions through analysis of 636 survey responses and 24 interviews with residents of MSAB in inner urban neighbourhoods of Brisbane, Australia. The findings show that the availability of natural ventilation and outdoor private living spaces play important roles in resident perceptions of liveability in the subtropics where the climate is conducive to year round “outdoor living”. Residents valued choice with regard to climate control methods in their apartments. They overwhelmingly preferred natural ventilation to manage thermal comfort, and turned to the air-conditioner for limited periods, particularly when external conditions were too noisy. These findings provide a unique evidence base for reducing the environmental impact of MSAB and increasing the acceptability of apartment living, through incorporating residential attributes positioned around climate-responsive architecture.

    This study focused on associations between insomnia symptoms, daytime napping, and falls in community-dwelling elderly, using a population-based cross-sectional design and probability sample with 689 community-dwelling elders. The protocol consisted of self-reported and physical performance variables. The study used univariate and multivariate logistic regression analysis with statistical significance set at p insomnia symptoms and daytime napping were 49.9% (n = 339) and 62.8% (n = 432), respectively. 14.4% reported a single fall and 11.9% reported multiple falls. Falls were associated with female gender (OR = 7.73; 95%CI: 3.03-19.72), age > 80 (OR = 3.48; 95%CI: 1.54-7.85), napping (OR = 2.24; 95%CI: 1.24-4.05), and depressive symptoms (OR = 1.98; 95%CI: 1.11-3.53). The association between daytime napping and falls corroborates data from international research. Identifying modifiable risk factors may help programs to prevent falls in the elderly.

  10. Dwelling-mobility”: An existential theory of well-being

    Directory of Open Access Journals (Sweden)

    Les Todres

    2010-09-01

    Full Text Available In this article we offer an existential theory of well-being that is guided by Heidegger's later writings on “homecoming”. We approach the question of what it is about the essence of well-being that makes all kinds of well-being possible. Consistent with a phenomenological approach, well-being is both a way of being-in-the-world, as well as a felt sense of what this is like as an experience. Drawing on Heidegger's notion of Gegnet (abiding expanse, we characterise the deepest possibility of existential well-being as “dwelling-mobility”. This term indicates both the “adventure” of being called into expansive existential possibilities, as well as “being-at-home-with” what has been given. This deepest possibility of well-being carries with it a feeling of rootedness and flow, peace and possibility. However, we also consider how the separate notions of existential mobility and existential dwelling as discrete emphases can be developed to describe multiple variations of well-being possibilities.

    Hörnqvist, Magnus; Viskari, Leif

    2014-06-01

    The effect of short-term thermal exposure on microstructure and dwell-fatigue resistance of Ni-base superalloy 718Plus was investigated. Contrary to previous studies performed after long-term exposure, an increase in the dwell-fatigue crack growth rate was observed, which was connected to a small increase in the size of the hardening precipitates. The proposed controlling mechanism was the stress relaxation rate at the crack tip, and based on this a schematic model for the development of the properties during exposure is presented.

    Myhre, L.

    1995-12-01

    Motivated by the need to reduce the total energy consumption and the environmental load from society, this doctoral thesis discusses energy conservation measures on existing houses. Alternative additional thermal insulation measures are assessed using an interdisciplinary life cycle approach. The first task is to develop an interdisciplinary assessment method for building improvement measures, taking account of energy consumption, resource consumption, emissions to air of environmentally harmful gases, and economic costs during the entire life cycle of the building. The second task is to develop an estimation model for the total energy consumption and emissions to air of environmentally harmful gases from the dwelling stock of Norway. Finally, the third task is to assess the total energy saving potential and the total environmental benefits of energy saving measures in houses on a national level, including only life cycle analyses of additional thermal insulation measures on single houses. Chap 2 describes the dwelling stock in Norway. Chaps 3 and 4 present an estimation model for total energy consumption and emissions to air from the dwelling stock, and calculations using the model. Chaps 5 and 6 propose and use a calculation method for the assessment of additional thermal insulation measures, using a ``cradle-to-grave`` approach. Since hydroelectric power is the main energy source in this sector in Norway, estimated payback periods for emissions to air are long. But hydroelectric power saved in this sector may be used to obtain reduction in fossil fuel use in other sectors as discussed in Chap 7. Some of the topics discussed are further elaborated on in appendices. 107 refs., 39 figs, 88 tabs.

    Future Linear colliders will need particle beam sizes in the nanometre range. The beam also needs to be stable all along the beam line and especially at the Final Focus section. A dedicated Final Focus test stand has been used for this study and is comprised of several sub-parts. First there is the Stabilisation/Isolation system with sensors and actuators stabilizing down to sub-nanometre level. Then the Magnet itself needs to comply with very specific design constraints. In addition to the mechanical items, the beam can be stabilized acting on the trajectory directly and Beam-based controls have been developed and tested on different accelerator facilities.

    The Cassini-Huygens mission, a joint collaboration between NASA, ESA and the Italian Space Agency, is approaching its last year of operations after nearly 12 years in orbit around Saturn. Cassini will send back its final bits of unique data on September 15th, 2017 as it plunges into Saturn's atmosphere, vaporizing and satisfying planetary protection requirements. Before that time Cassini will continue its legacy of exploration and discovery with 12 close flybys of Titan in 2016 and 2017 that will return new science data as well as sculpt the inclinations and periods of the final orbits. Even though all of our close icy satellite flybys, including those of Enceladus, are now completed, numerous Voyager-class flybys (summer solstice approaches. In November 2016 Cassini will transition to a series of orbits with peripases just outside Saturn's F ring. These 20 orbits will include close flybys of some tiny ring moons and excellent views of the F ring and outer A ring. The 126th and final close flyby of Titan will propel Cassini across Saturn's main rings and into its final orbits. Cassini's Grand Finale, starting in April 2017, is comprised of 22 orbits at an inclination of 63 degrees. Cassini will repeatedly dive between the innermost rings and the upper atmosphere of the planet providing insights into fundamental questions unattainable during the rest of the mission. Cassini will be the first spacecraft to explore this region. These close orbits provide the highest resolution observations of both the rings and Saturn, and direct in situ sampling of the ring particles, composition, plasma, Saturn's exosphere and the innermost radiation belts. Saturn's gravitational field will be measured to unprecedented accuracy, providing information on the interior structure of the planet, winds in the outer layers of Saturn's atmosphere, and the mass distribution in the rings. Probing the magnetic field will give insight into the nature of the magnetic dynamo, telling us: why the

Se ha comprobado el efecto hipotensor ocular de los cannabinoides al disminuir la producción de humor acuoso, y aumentar la excreción de humor acuoso a través de la malla trabecular y la vía uveoescleral, efecto compatible con el hallazgo de elevadas concentraciones de receptores de cannabinoides rCB1 y rCB2; además, el tetrahidrocannabinol ha demostrado disminuir el efecto neurodegenerativo en modelos de isquemia cerebral en ratas y se evidenció también el efecto beneficioso de los cannabinoides al disminuir la degeneración secundaria asociada al glaucoma mediada por la excitotoxicidad del glutamato. Estos hallazgos sobre el efecto beneficioso de los cannabinoides como hipotensores oculares y por su efecto neuroprotector, transmiten un mensaje esperanzador sobre la función que estos podrían desempeñar en el campo del glaucoma, aunque para mayor seguridad y eficacia serían necesarios ensayos clínicos encaminados a valorar su aplicabilidad en la práctica clínica diaria.

    To investigate the relationship between age, gender, history of falls, balance and gait status, general health perception, activities of daily living and depression to fear of falling in community-dwelling older people in Danang, Vietnam. Fear of falling is a common and consequential psychosocial problem for older people and can lead to decreased quality of life. There is only limited research on fear of falling in Vietnam. This is a cross-sectional descriptive study. One hundred fifty-three community-dwelling older people were recruited from seven communities of different districts in Danang. Data were collected using six instruments: a demographic questionnaire, the Fall Efficacy Scale-International, the General Health Perception questionnaire, the Barthel Activities of Daily Living, the Geriatric Depression Scale and the Timed Up and Go test. Data were analysed using descriptive and correlational statistics. The mean Fall Efficacy Scale-International score was 35, indicating a high level of fear of falling. ADLs, general health perception and Timed Up and Go were significantly and negatively related to fear of falling (rp  = -0·80, rsp  = -0·77 and rp  = -0·75, respectively). Age, depression and history of falls were significantly and positively related to fear of falling (rp  = 0·54, rp  = 0·45 and rs  = 0·39, respectively). Women were significantly more likely than men to have higher fear of falling (rpb  = -0·28). Fear of falling is more common in older people who are female, have a history of falls, have poor balance and gait status, have poor health perception, have greater ADL dependency, are depressed and, within the older people population, are older. Further research could examine additional correlates of fear of falling and develop/evaluate factor-specific intervention strategies to reduce fear of falling among community-dwelling older people. Understanding correlates of fear of falling among older Vietnamese people contributes to

  19. Geologic influence on indoor radon concentrations and gamma radiation levels in Norwegian dwellings

    Indoor radon levels in 1618 Norwegian dwellings located in different geological settings were compared with geological information in order to determine potential correlations between geological factors and indoor radon concentrations in Norway and to establish whether geological information is useful in radon risk analysis. In two geographically limited areas, Kinsarvik and Fen, detailed geological and geochemical investigations were carried out in order to explain their elevated natural radiation environment. Significant correlations between geology and indoor radon concentrations in Norway are found when the properties of both the bedrock and the overburden are taken into account. Areas of high radon risk in Norway include 1) exposed bedrock with elevated levels of radium (mainly alum shale and granites) and b) highly permeable unconsolidated sediments derived from all rock types (mainly glaciofluvial and fluvial deposits) and moderately permeable sediments containing radium rich rock fragments (mainly basal till). More than 20 % of Norwegian dwellings located in the high-risk areas can be expected to contain radon levels exceeding 200 Bq/m3. The elevated radon risk related to penneable building grounds is illustrated in Kinsarvik where the highly permeable sediments and the large vadose zone underlying the Huse residential area enable the transport of radon from large volumes into the dwellings resulting in enhanced indoor radon concentrations. Subterranean air flows caused by temperature/pressure differences between soil air and atmospheric air and elevations differences within the Huse area are shown to strongly affect the annual variations in indoor radon concentrations. The marked contrasts in radon risk potential between different types of building grounds are clearly illustrated in the Fen area where outcrops of the radium rich Fen carbonatites represent areas of high radon risk while only low levels of both indoor radon concentrations and indoor gamma

    Full Text Available El artículo explora los usos que del derecho colonial hicieronlos indígenas en la última etapa de este período de la dominación española, que va desde las reformas borbónicas hasta la Independencia (1750-1810. La primera parte, resultado de una revisión historiográfica, da cuenta de cómo la inicial pretensión del régimen colonial de conservar los sistemas jurídicos indígenas derivó en lacreación de un régimen jurídico diferenciado, que separaba la “república de indios” de la “república de españoles”; separación que, si bien no fue efectiva en preservar las tradiciones legales prehispánicas, permitió diversos usos del Derecho como mecanismo de adaptación y resistencia. La segunda parte del texto ilustra estos usos del Derecho, con algunas actuaciones jurídicas de indígenas a finales del siglo XVIII y principios del XIX en el Nuevo Reino deGranada.

    Full Text Available Objective. Insulin resistance (IR is a pathological condition present not only in patients with type 2 diabetes mellitus (DM, but also in community-dwelling population without DM. Both central arterial stiffness and IR are closely correlated with cardiovascular morbidity and mortality. The relationship between central arterial stiffness and IR has not been described in Chinese community-dwelling population without DM. The current analysis was designed to investigate the relationship between central arterial stiffness and IR in Chinese community-dwelling population without DM. Methods. There were 1150 participants fully assessed for not only homeostasis model assessment of insulin resistance (HOMA-IR but also carotid-femoral pulse wave velocity (cfPWV. Results. Median age was 39 (18–80 years, and 69.7% were men. Bivariate correlation analysis showed that cfPWV was significantly related to HOMA-IR (P<0.05. Logistic regression analysis indicated that cfPWV was independently associated with HOMA-IR (P<0.05. Conclusions. This community-based analysis testified that the relationship between central arterial stiffness and IR was evident as early as during nondiabetic stage. Early interventions in Chinese community-dwelling population without DM to improve the IR are also important in the prevention of cardiovascular diseases.

    [Purpose] Driving is a vital component of recovery for stroke survivors facilitating restoration of their family roles and reintegration back into their communities and associations. The purpose of this study was to evaluate the validity and reliability of the Safe Driving Behavior Measure (SDBM) in community-dwelling self-drivers post-stroke. [Subjects and Methods] Participants were sixty-seven community-dwelling self-drivers who had received a diagnosis of first stroke in the past twelve months. To investigate the validity and reliability of the SDBM, this study evaluated two sessions, held three days apart in a quiet and well-organized assessment room. Cronbach's alpha and the Intraclass Correlation Coefficient [ICC (2.1)] were used to evaluate statistically concurrent validity and reliability of the overall and three domain scores. Pearson's correlations were used to quantify the bivariate associations among the three domains. [Results] The Cronbach's alpha coefficients for the three domains of person-vehicle (0.989), person-environment (0.997), and person-vehicle-environment (0.968) of the SDBM indicated high internal consistency in community-dwelling self-drivers with stroke, in addition to excellent rest-retest reliability. [Conclusion] The results of this study suggest that the SDBM could be a reliable measure to evaluate automobile driving in community-dwelling self-drivers with stroke.
